I was diagnosed with brown sequard syndrome, but did not have a trauma accident...it just sorta happened. I have no feeling in my left arm but have regained some strength and some function. I only sweat on the right side of my body now. My balance started to get better, but now I feel like its starting to go backwards. Its been a little over a year since the injury happened, is it normal to make progress and then regress? Also I have returned to work, but I have a lot of back pain now. Would I qualify for social security disability?
