Hi Kelley -
My 52 year old husband had TBI January 30, 2011. His problems are identical to yours in many ways. The walking and sweeping you talk about set off his balance issues & cause headaches & fatigue. Sometimes he tolerates it better than others.

John is in physical therapy and he is finding that the more "rattled and fatigued" he is mentally, the worse his physical symptoms manifest. So if he had too much MENTAL / VISUAL stimulation one day, the next several days (or weeks) all of his physical issues are much more debilitating and prominent.

He is also EXTREMELY susceptible to major physical and mental "set-backs" if he undergoes any activity with the SLIGHTEST jarring to his body (trotting downstairs, walking too briskly, hammering something, riding lawnmower). All those activities have "vibrations" that go thru your body --- thus, your brain. When he does something incurring "vibrations" he will immediately OR the next day feel horrible and it can go on for days or weeks.

I think the issues you are having are pretty normal for post-concussion folks. You are definitely NOT alone. I'd suggest you try to find a doctor that specializes in brain injury rehabilitation to work with you.

I'm sure a lot of the folks on here will have great advice for you, and if you read some of the posts you'll find there are many others dealing with the same stuff.

Blessings to you...
Amy
