concussion question
 

i had a severe concussion about4 weeks ago after i got hit by a car on my bike and my head hit the concrete. today as i was sleeping i moved my head and hit it against the wall as i was turning. it wasn't too hard, but it was still a good hit. do you think this is something i will have to woorry about? my conussion occured on the back of my head and i hit myself on the front this time, btw.

After being hit by the car, did you go to the hospital?

If so, what did they say/do for you?

There is something called Second Impact Syndrome which is very dangerous. It happens when another concussion occurs before the symptoms of the first one resolve.

What are your current symptoms?

Your brain is more susceptible to injury after previous concussions, so it is possible that something could go wrong.

That said, I have bumped my head several times, panicked about it, and had no real change in symptoms afterwards.

Just pay attention to any changes you notice and be sure to mention it to your doctor just in case.

thanks for the replies. i have felt no side effects after my accident at all besides finding it harder to wake up from sleeping.

Generally speaking, if your symptoms do not worsen, you can relax a bit. But in these first few months, your brain's spatial awareness has decreased. This means being especially cautious about when and how you move. Move very slowly and deliberately. Eventually this will improve, but it will take time. Think about what is around you before you move (cabinets, doors, etc.)

If you notice your symptoms worsen, go to the hospital, otherwise forget it and get some rest.
