What Should You Do If You Think You Have Had a Concussion?

What exactly is a concussion?

Although there is actually no single, accepted definition of concussion, it is commonly described as a blow or jolt to the head that disrupts the function of the brain.

Also called a mild traumatic brain injury, a concussion can result from a car crash, a sports injury, or from a seemingly innocuous fall. Concussions can also occur when the head and upper body are shaken violently. Recovery times can vary greatly.

So, how do you know if you should seek medical attention or wait and see?

The best answer: when in doubt, get prompt medical attention. Lots of people may have a headache or dizziness for a day or so and then recovery fully, but a very small group of people who sustain a concussion — five percent — can develop bleeding or a blood clot that can be life threatening if not promptly diagnosed.

Brain injuries are extremely common, but diagnosis can be complicated. Today, there is no single, objective measure that can determine if someone has had a concussion. To make a diagnosis, professionals look at many variables that might indicate trauma,  ranging from changes in balance to memory lapses and dizziness.

It’s critical to seek immediate medical attention in a hospital or emergency department if any of these symptoms are present:

  • Loss of consciousness, even if only briefly
  • Any period of amnesia, or loss of memory for the event
  • Feeling dazed or confused
  • Headache
  • Vomiting
  • Seizure
  • In addition, for children under 2 years of age, any scalp swelling or abnormality in the way they usually behave.

And if possible, see a medical professional who has knowledge of and experience with brain injury.


Depending on your symptoms, your age, and the severity of the injury, the emergency department physicians may order some tests. Here are some of the most common:

  • Neurological test– A basic neurological exam in the ER assesses motor and sensory skills, the functioning of one or more cranial nerves, hearing and speech, vision, coordination and balance, mental status, and changes in mood or behavior, among other abilities. 
  • CT scan– A CT is a special computerized x-ray that provides images of the brain and is sometimes used to look for suspected bleeding or swelling.
  • MRI scan– A Magnetic Resonance Imaging test provides detailed pictures of the brain using magnetic energy instead of radiation.

Even though someone has had a concussion, the MRI and CT scans are often negative. That does not mean that there is no injury; it just means that the damage is not visible on the scans.


Simple though it sounds, rest is the best treatment we have today for a concussion.

If you think of the brain as an engine, it runs out of gas faster after an injury. Rest is the only way to fill up the tank again. So, the best way to recover is to rest.

Rest is important because the brain continues to heal even after all the symptoms are gone. At least initially, rest means not reading, not listening to music, not watching TV. It means no texting, no email, no cell phone. Rest means physical rest AND cognitive rest.

That said, if symptoms persist — headaches, nausea, dizziness, balance problems, confusion — after you have gotten medical care, call your healthcare provider again. Be persistent and find a healthcare provider who specializes in treating traumatic brain injury.


Most people who sustain a concussion or mild TBI are back to normal often in a week or two and almost always within a few months. But others can have long-term problems either from the concussion or from injury to surrounding soft tissues.

The sooner someone is diagnosed, the better the chances for a good recovery because rest is so important

One word of caution: Because a concussion affects the brain, the injured person may lack the clear judgment to make an informed decision regarding whether or not to go to the hospital. Family and friends can be instrumental in urging him or her to seek medical attention. Remember, when in doubt, check it out!

I hit my right frontal lobe over a week ago and within more or less 2 days I started feeling symptoms of a concussion. I am in fact 12 and am taking my standardized test but it's on a computer what should I do?

I am almost 14. Today i got hit on the head with a ball with a soccer ball. I was sent out of the game because I wasn't feeling to good and I am researching if I have a concussion.

I just got in an auto accident today in FtW TX (I was rear ended and got shoved). The accident appeared minor, but the back of my head hit the seat. When I got out of the car, I got dizzy and I afterwards threw up and started to have cold sweats. Part of me thinks it is shock of the accident, but part of me is concerned: What if? The police dismissed the accident as minor, but I am still in pain and I am concerned. I asked my work mates and my husband to watch me the next couple days to see any abnormalities in my behavior. I can't afford a CT scan. The insurance told me it is up to me if I seek any medical tests, but I have to pay for it. What should I do?

So we got a new horse a few days ago and I usually ride my quarter horse but I decided to ride the new horse (thoroughbred/quarter horse) and she was doing fine all the times I rode her, but today I was riding my horse and I told my dad to get on the new horse so we could ride together, he got on her and she started bucking, he fell off of her and hit his head really hard on the hard dirt. I watched it all happen and he told me that he has pressure in the top of his head and he kinds has a headache and he feels funny. I believe that he has swelling and I gave him ibuprofen but I'm starting to wonder if maybe he could possibly have bleeding inside of his skull.

I am 16 years old and I am from a rural village in Alaska. On October 8, 2016, I was in a bad quad accident. So, me and my two friends were going on this road near the village and it's was past 11pm so it was dark out. So anyway, I know that we were going pretty fast and we didn't know there was another quad ahead of us because they left their lights off. We bumped into them hard, really hard. I landed on my head on hard gravel and fractured the bone above and below your eye. There was bleeding somewhere in my skull and it was putting pressure on my brain so I got transported to Anchorage, AK. The neurosurgeons told my parents that I have a 50% chance of making it and they are grateful that I have pulled through. Still recovering. -Tim

I am currently 16 years old, and even being this age you would think Ii would have some kind of knowledge of what not to do in a Kroger store, or any store for that matter.....but no. I was with my best friend, I took a balloon that was floating as a decoration...and sucked the helium out of it. About 4 inhales later, I passed out. The last thing I remember before hitting the ground was a shelf of detergent. I woke up confused and a little scared. An older man was tapping on my shoulder I think, I cant fully remember. The side of my head hurt but the next day I noticed a knot on the back of my head so I question myself as to which way I had fallen. Luckily I had a thick head band on and my injury wasn't too serious. I do however have a headache still, and this is the day after the incident. But after doing some research, I am a tad afraid that I could have more critical results, I could just be paranoid.

i was walking my dog and there were three dogs walking passed us and I had to hold him down because they where trying to go after him, and he popped my jaw closed with the back of his head, it stunned me a little and I had to check to see if I still had all my teeth but ever since then I get random pains on my left side of my head... It's just that, no other signs. And the pain doesn't stay, it's there and gone in an instant, but it happens frequently. Nothing really triggers it. If I take pain killers it'll go away but come back after the meds go away.

Well I play football currently (I'm only in 8th grade so usually nothing bad like a brain injury happens) and during today's practice I had a few hard hits like when my head hit the ground a few times but the one that made me have to take a breath was a collision with a linebacker, I told the coaches that my head hurt a few plays after they asked if it was a concussion and at first all I did was say I don't think so. They asked again and I said no. Later after practice I came home and felt tired and really pukey I was gonna take a shower but I couldn't stand because my feet hurt so I took a bath, during the bath I fell asleep and woke up about a half an hour later. Now I'm looking up the symptoms and as I'm reading them I'm realizing how I forgot to do anything in the bath besides sleep and I'm laying in a dark room with a bowl next to me in case I puke. Please help me, I have no idea what to do.

Aug 29th, 2016 8:48pm

My botfriend hit me in the head a few times very hard. Yes i have left him and yes, i have had a concussion because of it.

Aug 19th, 2016 3:55am

After hitting my head hard and looking for advice, I read through these comments. Now my only concern is for the girl who said your boyfriend hit you hard in the head, for the second time. I really hope you found the strength you needed to leave him. You do not deserve that, nobody does.

Jul 28th, 2016 10:41pm

Wow.  I lost consciousness, had a seizure and suffered amnesia when I fell off my bicycle 35 years ago.  I haven't thought to tell any physicians.  I don't see what good it would do now...  I do suffer from depression and anxiety which developed in the years shortly after, and I take medication for that along with Nuvigil which helps my overall functioning immensely.

Jul 10th, 2016 12:08am

Just reading the comments in that font hurt my eyes and head. I was wakeboarding today and fell hard a number of times bc it was my first time and even though I was wearing a helmet, my head is still pounding and I feel super tired but I'm not sure if its just bc I was wakeboarding for 2 hours. I only hit my head on the water, not the jumps but it was technically cable boarding so it was a really rough start. it jerked you onto the water so fast, it was very hard for me. wish i could see the doc but don't know if i need to.

I have had 10+ concussions from low speed impact car accidents, falling, hitting a refrigerator, someone dropping their suitcase on me etc. over the years. After my last one I couldn't understand anything I tried to read. I found a clinic that provides hyperbaric oxygen treatments & went for 10 sessions. By the 8th treatment I could read, follow conversations, sleep comfortably, headache was gone, could type & felt more energetic. Read "the Oxygen Revolution, " by Paul Harch M.D. and find out what kind of healing is possible for yourself- regardless of how old your injuries are.

I tripped at a concert on the way out of the venue and they had set up a makeshift walkway which had a metal template sticking up out of nowhere. Anyway my flat sandal was stuck and i fell backwards and split my head open and broke my tailbone and my back has been killing me. I just had a second cat scan because my head has been killing me. I had 8 staples in my head and that was nothing compared to this pain believe it or not! My general practitioner didn't know that this had happened but when I saw him recently he looked at my right ear and asked if something was going on! I had noticed a swishing sound and off balance in my life and he saw a hemmorage there so that is why i had a second ct scan today...This accident happened 2 and half months ago..wow. .that shows you how long it can take for a hematoma to occur very scary..

Jun 17th, 2016 2:09am

Very helpful. Thank u

May 27th, 2016 2:28pm

When I was 12 years old I was playing  football and I got hit in the head pretty hard. I blacked out on the field and didn't wake up till 6 at night. I had concussions before that to but not like that one. I had the concussion for 2 months. Everyone is different and will get different symptoms. I'm almost 19 now and I have short term memory loss and I still play football.

May 25th, 2016 9:24pm

My boyfriend hit me hard in the head. The next day I was dizzy, sleepy, slurring my words. This is the second time he has done this. The first time I felt even worst. I was even scared to drive. Can you get a concussion if you get hit in the head hard enough??

May 17th, 2016 6:24pm

My perspective: Doctors nowadays are so overworked and overwhelmed they seem to want to give patients the bare minimum of their time.

Apr 26th, 2016 8:30am

I fell in my home and broke my toe and hit my head. I went to the urgent care. They x-rayed my toe, but didn't want to hear anything about my head. I had a low grade headache, but no bleeding and no lump. I never lost consciousness. The doctor sort of berated me for wanting him to look at me, and tell me what to do about my head injury. Next day I'm feeling a little more confused and foggy, but I still have my memory and my pupils look normal, no vomiting, but I am a little cranky. Hard to know what to do when the doctors make fun of you for wanting advice you're told to get in this sort of situation.

If forming a blood clot has no symptoms, outside of a $3000 CT scan or MRI, how will the Dr determine this? Serious question, I would like to know. :)

Apr 3rd, 2016 10:27pm

Folks, a lot of you here have had concussions of varying degrees of severity. If your TBI was long ago, there's not much you can do. If it was recent, go to the doctor, just to make sure you have no bleeding or blood clots forming. These events may have no symptoms but could be progressive and could cause death within a few days. Your brain is fragile and just a moderate amount of it banging up against the cranial wall can injure tissue and blood vessels, helmet or no helmet. Please take this seriously.

I have had my third concussion via motor vehicle accident. They are not my fault. This last one I flipped my suv after taking a seizure. The seizures started from being rear ended at a stop light. The doctors were not keeping an eye on my seizure medication levels and I had a seizure while driving. Thing is , I have been to the doc after five days in hospital complaining about post conclusive headaches and they just tell me oh you have brain injury. I have been back twice now. Next told it is just worsening of injuries from first motor vehicle accident. Come on I was knocked out in hospital five days. Am in severe pain help me. Any one else feel like they are talking to a brick wall. Oh ya. I did go to Physio at first, but the therapist was making me do things that brought on concussion symptoms like vertigo vomiting fainting and worsening of pain of other injuries I had to quit going all together. So in six months since the accident I have not had proper physio care. My head injury from my worse accident has left my skull with a Teflon plate on one side and brain gliosis or bruising in both temples and frontal lobes. My EEG show significant brain damage from past head injuries that it was commented on I needed to be careful. As well as I needed a referral for a new neurologist to be seen every three months. And this is Ontario Canada. Any one else having similar situation

Feb 22nd, 2016 4:15am

I hit my head snowboarding  and went to the doctors the next day and the doctors didn't do anything about it and then i went to the hospital on two days after i hit my head and after my headaches and vision got worse. The hospital didn't do a MRI or CT scan they just told me i have a concussion. Like who knows if i have anything wrong with my brain. It was so stupid and now i will never know if i have anything wrong with my head 

Feb 9th, 2016 11:01pm

My neurologist said bleeding is always present and seen by an MRI no matter what. I fell six feet right on my temple- full force. He lied to me.

Jan 20th, 2016 4:18pm

I am fourteen and have had two concussions which were two months apart. first one was in july and was a grade 3 concussion and second one was in september and was a grade one concussion. i am still not allowed to play sports. It is a bad excuse to get out of school!

Great help informative

Find an osteopath who does cranio sacral therapy . I was hit by a car when I was cycling and had a concussion . After just the first session the confusion and disorientation and vision problems improved . After the second session the dizziness was gone. The bones in the skull are gently repositioned Fabulous therapy

I have had 3 car wrecks and got ran over by a car all before I was 15 and a few days ago I hit my head and it didn't seem like a big deal but from all my head injurys I can't remember a lot of things so my head hurts and my stomach was sick and I was a little blurry but now I don't know what to do it has messed with my mind so much I can't remember a lot and I have children what should I do

Nov 2nd, 2015 8:44pm

Can your eyes still be blurry if u have a concussion? But now show on ct or mri

Oct 8th, 2015 7:43pm

I've had 4 concussions, just by the age of 16. My most recent one was the beginning summer. All 4 of them have been because of soccer. I was wondering if i should continue playing?

Sep 21st, 2015 8:11pm

I've gotten two concussions in my life but I don't remember exactly how they happened. The first one was when I was six, I was swinging and I remember going very high before I blacked out. When I woke up I was being carried inside and I last consciousness a few more times after that because the pain in my head was so severe and eventually I vomited. My parents figured it wasn't really a concussion and never took me to the doctor. It wasn't until years later when I got another concussion (from falling and heading my head against the bottom of an empty pool) and I complained of chronic headaches and memory loss that they finally took me to see someone. Now I get a nasty headache almost every week and my long term memory is much worse than it used to be. Make sure to get yourself checked out if you get a head injury because the after effects can last for years, if not indefinitely.

Aug 3rd, 2015 12:39am

Sounds like you have a traumatic brain injury. TBI is nicknamed the invisible brain injury but symptoms are real and permanent. My husband was in a car accident in 2006 and simply told he had severe concussion...two years later he was properly diagnosed and has a team of doctors now helping with every defficit he faces. Study TBI...it is permanent brain damage.

I was involved in a car accident as a passenger back in 1987. A drunk driver broadsided our four door car. The rear passenger door buckled and my first reaction was turning my body to the left to get out of the seat. My head went into the windshield and left a round spidered circle. I was knocked out but had came back as the car was in a spin for a ditch. The car went through a barbed wire fence into a farmers field. Although shaken up I did not go to the hospital at age 11. The following days I had headache and nausea and slept straight for two days. I was a kid and felt invincible up to that point. Then fear started to take over. My outlet was sports and I wasn't going to let fear take me over. But the fogginess and confusion still persisted for months later and a loss of short term memory. Long term memory became excellent to almost supernatural. Years later I had CT scans and mRI scans done. Nothing showed. After high school I quit sports altogether then noticed how much has changed since with mood, emotions, and irritability. There are long term effects that need to be recognized with concussions and I hope someone does studies on this.

Jun 19th, 2015 12:42pm

My husband hit his head on a low beam in the house ten days ago he was nausea, confused, exhausted, forgetful he's gradually getting better with plenty of rest over the four days post the inccident he came home after the first full week back at work and fell asleep 19.30 last night it's now approx 8.00am on the next morning and he's still asleep he's 34 and very fit and healthy is this just part of the recovery?

Jun 13th, 2015 2:58am

My husband fell forward on concrete at work. He softened the head blow with his arms. A man ran up to help and kicked him in the temple with a steel toe shoe. He was trying to help. I believe he had a concussion. Sleeping a lot, memory issues, or just didn't make sense! I have never delt with this. And he is pron to blood clots. After over 2 weeks he is better. Neck and head still hurting. He also broke his toe and still made him work!

May 28th, 2015 1:50am

I've had 10 or 11 concussions over the course of my athletic career, and the biggest mistake I ever made was rushing back to play again because I felt "fine." If you've had a recent concussion, you're now much more susceptible to a severe concussion from even a mild blow to the head. I know - it happened to me. The second one was a mild bump and it rendered me unable to work or think for a week. Scary. I post this now because I just fell from 10 feet during a CrossFit competition (hands slipped on the pull-up bar), and now I have to decide how quickly I can get back in the gym. My ego tells me I'll be good to go tomorrow, but my experience tells me to wait a week at least.

May 25th, 2015 4:03pm

Sounds like some people on here have had or have concussions, I"m not a doctor only someone suffering with a concussion.  To answer the questions as to why they haven't gone to the emergency room or doctor or whatever, with my concussion I've found, I have needed someone to tell me what to do, for some reason I wasn't able to make the decision for myself.  Part of myself kept thinking I was making a big deal out of nothing etc and part of me knew I should see a doctor but until someone told me to make an appointment, I was unable.  Anyway, if you think you may have a concussion go see the doctor and tell him how you are feeling.  I was in a car accident, I had not visible injuries and no one thought to ask the right questions regarding concussion, I thought I was fine, just in shock maybe, but I wasn't.  So call!

Jan 9th, 2015 11:15am

Is there a specific time frame after the injury that vomiting would occur?

Dec 23rd, 2014 10:17pm

Get a ct scan, make sure theres no bleeding. And rest, stay out of gym.

Oct 23rd, 2014 12:55am

Come on people a bit of common sense is needed here writing in the comments box isnt going to get you a reply from a doctor if your unsure about going to A&E ring the out of hours or non emergency and they will tell you if you need medical attention

Sep 10th, 2014 11:58pm

Jesus people, yes you have a concussion. I've had several and all of your symptoms sound much worse than what I was experiencing, or on par with the worst one.

Aug 27th, 2014 7:42pm

Good Grief.  If you are asking if you need to be seen by a doctor, then you need to be seen by a doctor.  

Aug 21st, 2014 3:03pm

Go to the doctor right away, even if you're feeling mostly better. Its your brain - you will be sorry you took extra precaution. Please see a doc.

Aug 18th, 2014 9:01pm

Thats a graet help thanks i really needed that thanks x

Jul 18th, 2014 6:28pm

I am 12 and got a one when playing soccer. The doc said I would be able to play in a week or so but after a week I was still not feeling good so my mom took me agian and they ened up saying I wasn't aloud in loud places so I couldn't do anything or be around anything that is really loud.

Jun 18th, 2014 9:21pm

I'm 18 and I got bashed in the nose by someone's head at Rockfest yesterday. The doctors said I have a mild concussion but I've never been injured before so I'm a little worried and freaking out just a bit. I'm hoping because I'm  young and relatively healthy it won't take long to heal. My work isn't going to let me have any days off for it, I'm sure. :/

Jun 1st, 2014 8:11am

I am 29 years old and I crashed a dirt bike going over a 9th jump and Landed on my head. I knocked myself completely out. I woke up 17 hours later in a hospital. CT scan was normal. Good thing I was wearing a good helmet and my neck brace or my neck would be broken for sure. 2 weeks later I still have symptoms. Doctors say it's normal. Takes a while for the Brain to heal up!

Apr 7th, 2014 5:37pm

My experience is that what happened to me was summarized as Organic Brain Syndrome. For me, caffeine works a little to temporarily improve the ability to pay attention and comprehend a little better.

Nov 14th, 2013 8:52am

My head got slammed in a car door tonight by accident. I think that I may have a concussion. When I was younger and had one the dr. told me not to go to sleep for 2 hrs. after it happened. So that is what I am going to do. Wait 2 hrs. before going to sleep. I had a pounding head ache prior to this happening tonight too. :( So this just makes it feel worse.
