Lately, I've been having pain in the right wrist on average about a day or so after playing bass, for 3-4 hours. I haven't played for weeks because of it. A few months ago, I discovered bone growth on the back of my wrist (carpal boss) which, based on what I researched, is due to arthritis. To give a little background of myself, I've been playing bass as a hobby on and off since 2004, and have learned how to play from books and videos. In addition, in college, I had to make basswood models for Design class, mainly using my right hand with a blade to cut the pieces of wood to place together, which would also contribute to pain. I am also in the habit of lifting heavy objects, and have been using computers daily. I'm not sure which of these (or anything else) led to my arthritis/bone growth. I do calisthenic exercises and stretches in general, even before playing bass. Lately, I have researched that playing bass with my (right) wrists bent while sitting down is poor technique (please confirm?), and have stopped - I believe this has been the main contribution to the problem, but there could be other factors that I'm not aware of. I also browsed the stickys here, though carpal bossing doesn't seem to be brought up very often. Does anyone have carpal boss or general wrist pain as well? Please give me any advice. Thank you in advance.
