I'm a 6 foot 3 cellist, so I'm constantly getting back problems from not having big enough chairs! Playing the tenor sax probably doesn't help much either. It got really bad a couple of years ago, to the point where walking was painful. I'm more careful now to stop and sit back whenever I feel my back playing up. Other than that, I've been lucky enough not to damage anything seriously.
I've also got all the standard complaints: blisters on my left hand, bruised left thumb (too much thumb position practise

) etc. I play clarinet too, and over Easter I played so much my lip bled, which was a bit silly. I've also got a lovely dome of dead skin on my right thumb, from where my clarinet sits.
Ah, the things we do for our art
