When Can We Stop Worrying After a Hit on the Head?

Ask the Expert: When Can We Stop Worrying After a Hit on the Head?

About a month ago, my wife tripped while hiking and hit her head. We went to our Emergency Department and they did a CT scan, which was “clean.” Other than an occasional headache, my wife feels fine. Is there a time when we can stop worrying?


The CT scan that was done in the Emergency Department is helpful because it showed there was no bleed in your wife’s head (hemorrhage) that would require surgery. That being said, most of the time after a concussion — or mild brain injury — a CT scan does not show any evidence of injury and yet some people may continue to have symptoms related to the concussion. The injury to the brain in a concussion is generally to the neurons and axons that are microscopic and therefore not seen on CT scan. Symptoms can be broken down into four categories:

  • Cognitive issues, including memory and concentration
  • Sleep issues, including too much or too little sleep, drowsiness, and difficulty falling asleep
  • Physical issues, including headaches, decreased balance, dizziness, impaired vision, fatigue, nausea/vomiting, and sensitivity to light and noise
  • Emotional issues, including irritability, sadness, and nervousness

Many symptoms from mild traumatic brain injuries resolve themselves with some time and rest and it seems this is the case with your wife. However, if her headaches do not continue to improve, if they are limiting your her function, or if they worsen, it would be appropriate to take her for a re-evaluation by your physician.

My mother got on a motorcycle accident 3 days ago and hit her head on the concrete road. She felt dizzy after the impact she got on her head just right after it happened but she doesn't fell dizzy anymore until now. There was no bleeding or cut in her head, she has no other issues except from the swelling and redness/ bruised in a small part of her head.
I just want to ask if, is there anything we need to worry about or is it just a simple bruised regardless of the strong impact she got?

I hit my head multiple times 2 days ago and now I feel a slight numbness to it. My head feels heavy.

I slipped on a watery floor 6 years ago and hit my head on the outside corner of the couch.. I was hurt but no bleeding so I rubbed it out and went to bed.. today my head is itchy at that spot and tender.. I still have a slight lump there where I hit it.. should I continue to feel like it is healing?

Hi, i slammed the corner of my car door onto the left side of the back of my head today. It was with force. I heard it crack and the pain shot right through the point of contact. I was fine immediately after. When i returned home I came over all dizzy and a little nausous, without vomitting. I have had a dull pain all day with off shots of sharp pain now and then. I can feel a slight dent where the car door hit my head and it is painful to touch, a very sharp pain when i touch. Do I wait and see how i feel or is it quite important to be seen

you heard it crack??
you should definitely get seen immediately because it seems a lot of damage has been done

Get to a good optometrist and have them dialate your eye. Floaters are a sign of retina problems that can be helped but not if you wait.

I'd suggest a retina specialist
