Also, every relapse regardless of the reason triggers some intense pain (say 7 on a 1-10 scale) at the point of impact of my latest concussion 9 months ago (side of the forehand). Is it normal with PCS or is it a sign of something more serious, like bruising in the brain? (I did not have any image done after this hit). If is as if I could feel some swollen region behind my forehead.
