Hello and welcome to JustAnswer,
there's nothing about marijuana that will make the results of your concussion worse.
how severe was your concussion/
how did it happen?
how long were you unconscious?
then you have nothing to worry about and i wouldn't even say you had a concussion .
except for the headaches...
but with a normal ct scan you are okay.
no way to answer that.
some folks have headaches for months or even years.
does tylenol or motrin help?
then that is fine to take....
and by the way, i have been to your country, it's wonderful... my sincere condolences over that madman going on a rampage yesterday.
