The only major problem that I have had occurred when I first started playing the fiddle. It seems that I was using too much pressure with the chin to hold the fiddle. The result was FIDDLERS NECK and I ended up spending three days in the hospital before I could get up and about. I thought I was coming down with meningitis because I had extreme pain whenever I moved my head. It seems to be a rather rare problem & I have only met two other fiddle players who have had FIDDLERS NECK. There are quite a few chin rests on the market that allows the player to elevate the head while playing. My remedy was just to use as little pressure as possible on the chin rest.

I think its a good idea to play a variety of instruments and not stick with any one for an extended period of time. That way you don't get the repetitive movement problem. I have had carpel tunnel in both wrists. One was operated on and while I was waiting for that one to heal the other (left) wrist cured itself. I have no idea why that happened other than just giving that wrist a good long rest. Now days I switch instruments about every fifteen to twenty minutes.

Good luck.............Cap't Bob
