Hi doc I wasn't seeing where I was walking just know and bumped quite hard on my forehead to the wall. After that I started to get a little worried about internal brain bleeding to death and conscious . Then my left side of my head feels weird , I gamed for 5 hours before I was in bed and I just want to make sure if I'm OK because its really late now.

There is no way for us to know if you are OK or not. If you are worried, you need to go to the ER or see a doctor.
