Hi, i am a 23 male, about 4 weeks ago i hitted my head pretty hard twice, i was also so drunk i couldn`t remember anything. I've been to dr twice now, in both cases they told me everything is fine and that i should be well soon.

I feel completely normal except the stiffness around temples, might be jaw or upper neck aswell, not sure the feeling tends to spread whenever i try to concetrate on it, and the constant ringing in ears(tinnitus). I am most worried about my tinnitus since the high pitch tone has not changed during this 4 week time and my head feels the same everyday.
Also the stifness tends to start after few hours if being awake.
I don't have any problems falling asleep since the the constant ringing usually tires me out completely by evening.
I also started taking vitamins and cod liver oil, also picking up magnesium today.

Is it possible that i've gotten myself permanent tinnitus, or do these symptoms fade with time?
