After my mTBI no doctor asked me to rest and told me to do what I can. May be that was a mistake but I don't know but I was making progress with headaches, dizziness etc., After 5-6 weeks I went down just like that.

Then I rested for 1 year doing nothing and trying all kinds of meds/supplements and things didn't improve much at all. I got into depression and anxiety just because of that.

After that I slowly started doing stuff and now I can do elliptic for 15 minutes (started with 3 mins), some light weights and my heart rate doesn't go crazy anymore. My BP used to be 130ish/75ish and now it is around 120/60. Not sure it doing anything for my dizziness,imbalance or forehead headaches, eye strain but overall sure exercise helps a lot.

My primary doctor wanted me to go for a Neuro-rehab when she saw my condition. But no specialists even mentioned that. I should have followed my PCP advice. Still not sure why for severe TBI the new protocol is to start the rehab as soon as possible (even within few weeks) and for concussion you have to rest (both are brain injuries). But Buffalo protocol says different.

I think the best way to find out is to try slowly if the recovery didn't happen in about 6 months.
