I posted a fairly long thread on the brain injury thread about my numurous concussions and my headaches so I won't here.My question is this with my last concussion from a fall backward (7 years ago) The sypytoms cause me to see only a white haze for a while and my vision in a slow spin and not being able to open my eyes for 2 hours. Could these 5 or more concussions be the cause of very regular headache. The kind where it feels like there is a axe in the right side of my skull.
