This is my second concussion and the symptoms are lasting alot longer than they did during the previous one. Both were sustained during football. After the first I had trouble reading and typing (which i still have trouble doing), now after this one I have issues with balance, coordination, memory (someone will tell me something then 10 seconds later I cant remember it), lack of motivation and sensitivity to light and sound (all of these leading to depression). CT and MRI Scans negative for both for both concussions, but Im positive something is wrong. Wondering how long these symptoms will last? And if I will ever return to normal.
