between the concussion and acquired brain injury, I was lucky to avoid any cognitive difficulties, at least I think so. but the sensory symptoms - tinnitus, parasthesia, burning pain, fatigue from terrible sleep - are quite incapacitating. it's been 7 years and athough I a going to take marks advice and to to physiatrist, I have to decide for my peace of mind whether I will work again or not. I do not have kids or much family near me so it is quite hard to keep busy and get company so work was my personal as well as business life. don't know what to think. I was able to work after concussion. the abi did me in.
