It's been a year since my MTBI, and I decided I would try to exercise to see if my body could handle it. I had been jogging/walking pretty regularly so I decided to try lifting again. I lifted heavy, and it brought back my physical symptoms. I now have headaches, dizziness, balance issues, and increased sensitivity to light, sound and movement. This was 3 days ago and symptoms are still present. :\ Anyone have any suggestions? I am starting rehab to try to gradually get my body and mind back to a place where it can handle exertion.
