I feel you. My toes went numb on a hump once and they've never fully come back. I've been out since 2012 and still have the shoulder pain and numb toes so I'm not holding out for that pain to go away.
Have your Sciatic nerve looked into. I had a pretty bad bike crash (doored going 30mph, bounced on pavement with left hip). I would have burning sensations about the size of a fifty cent piece in my upper back, numb toes, etc. After 10+ years it finally subsided. Chronic pain is highly correlated with suicide. So best to get that fixed.
