It is really hard to say not knowing personally about this STS. Has he had any injections, PT, tried any medications etc? Does he see a psychologist for the depression part? It is a hard disease to treat and fight on a daily basis. The people on here know 1st hand and between all of us, there is nothing that hasn't been heard of. Don't give in and don't give up. It may take a while to try a bunch of stuff to get where he can manage the pain, not cure it, but it can happen, he needs to find a good doctor and try a lot of combinations of things. But do a search at the top for STS or start a new thread topic STS and I am sure you will get replies.

Good luck to you both and keep us all posted please. We will keep you in our thoughts here!!
