As someone with a chronic wrist problem, I think you are doing the right thing by cutting back and going to see a doctor. If it is tendonitis or something like that, then even though it doesn't hurt much now, if you continue to do the same things despite the pain, it will get much much worse and then you will have to cut out a lot of what you are doing and it will take months to recover (I don't even know how long it's been since I picked up my knitting needles). Also take some time to make sure the ergonomics of your computer desk are good, and your technique for music is good (not too much tension in the wrist). Since it is your right hand I might also suggest switching the mouse to your left hand.

Anyway, good luck, hopefully your wrist will recover soon!
