Hopefully it gets better with time for you. My complaint wasn't with pain, but numbness. I developed this problem very early on, in SOI, and kept it to myself because I knew that it would get me medically discharged. Thankfully I never had to explain to anyone why I'd go to the lengths I did in order to avoid handling grenades. After 2 years of civilian life my knees and lower back stopped bothering me, but 15 years later: my hands still feel like they're falling asleep.

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.
