Two years ago I got into an altercation and it

Patient: Two years ago I got into an altercation and it left a small bump On the left side of my head. If feels sort of like a cist, about a year and a half ago I noticed I had an indent In the very middle of my head, I went to a hospital for it and the nurse tried to say it was just the shape of my head but it wasn’t shaped like this before 2 years ago and when I get headaches now that’s the only place it hurts and it happens atleast 2 a week, it’s sometimes unbareable . It doesn’t hurt when I touch it Infact sometimes that helps it not hurt so bad. I don’t think it’s just the shape of my head

Doctor:
