So far, nothing. If stuff had worked, it's unlikely I would be spending so much time looking at this forum (pardon the dark sarcasm).

My symptoms mimic RSI, in that if I avoid problematic activities, the pain goes down fairly quickly. The trouble is that so many activities cause pain that I end up more or less partially disabled.

Right now I am on a program of lots of myofascial release, pieced together from my physical therapist, some books, and my own experience. I only started a couple weeks ago, and so far I haven't noticed a ton of benefit. But on the other hand, it doesn't seem to be making anything worse, and given my past experiences that's a step in the right direction.

Sorry I can't be more helpful.
