I'm an acupuncturist here in Los Angeles who has helped musicians, weekend warriors, and massage therapists get relief from repetitive strain injuries.  The key to effective treatment is understanding the whole body, particularly the "bad habits" of the upper body in relation to the lower body.  Learning new behaviors is the key to preventing future recurrences.  When looking for an acupuncturist to help with repetitive stress injury, it helps to ask how you will be treated.  Simply inserting needles at the site of pain will do nothing to address the root problem, which is structural and behavioral.  

In my previous personal struggles with carpal tunnel like symptoms, I found that certain foods actually irritated my hands.  I also found that the exercises supposed to prevent carpal tunnel actually exacerbated my symptoms.  That was till I took sessions with a specialist in the Alexander Technique.  

The point here is that often the culprit is much more complicated than appears.  Approaching the condition holistically will go a long way toward getting at the source of the problem.  Structural challenges that arise from work are certainly the most prevalent reason for repetitive stress conditions.  Working with a holistic practitioner can stop pain, ensure that exercises are performed correctly, and identify any contributory factors to make your recovery complete and lasting.
