help! I'm sleeping alot, is it because i hit my head?

Does a head concussion cause a person to sleep a lot? I got into an accident and hit my head 2 months ago, last week i fell down the stairs and hit my head on the wall, now I'm sleeping a lot, what does that mean?

Yes.  Concussion can cause anything and everything.  Probably your brain wants to heal and listen to it.  Most importantly go get checked out by a Neurologist or concussion specialist.
