My wife has constant pain. She describes most if it as "joint pain" and some in her right arm as "nerve pain". The joint pain has been around for about a decade and the right arm pain for about 3 years, ever since what certainly looked like a repetitive stress injury at work (lots of mousing with a desk that was too high).

Doctors have checked her out and haven't found a cause for either. Our possible next steps are:

• Get 2nd (actually 3rd-4th) opinions from local doctors. This feels futile but may still be helpful.
• Hire a doctor whose job it is to actually track down a cause and treatment, not just check for the common, easily detectable possibilities and then effectively give up. I'm not sure how to go about this but it feels like it should be possible for some price.
• Find plausible non-harmful self-treatment options and try them. Possible examples have recently been posted here on NancyLebovitz's Two angle's on RSI.

Suggestions, recommendations, places to look?
