And why wouldn't it be? Pain in your hands is still pain in your hands, whether it comes from fretting, plucking, picking or bowing.
My best advice would be to play shorter sessions, or at least take regular breaks to stretch and relax your muscles. When we are in the same position for any length of time, I think we tend to build up muscle tension.
At any rate, I am also interested in hearing what others have to say on this topic. I have carpal tunnel, tendinitis and arthritis (I call it the "triple whammy") and have had to learn to be gentle with myself. As tempting as it might be for me to play several hours straight, I know my body just can't handle it.
