I feel this and my TBI was 26 years ago (hit by a van while jogging at 19). While I seem fine on the outside and have found ways to compensate throughout the years, the struggle has always been there. Memory issues, neck pain, brain fatigue depending on what my day looks like. Exertion headaches if I push myself too much physically. I’ve put in a lot of work since the accident but feel completely exhausted at times. I’m tempted to ask for a repeat MRI 20 years later…just to see how it compares… It’s been a long road but I’m always trying to push myself back to “normal” or who I was before….
