I am no expert in this area but if it is the punching that is causing your arm pain my guess would be your punching form may be a little off. If your wrist and arms are not in proper position to spread the force from the impact through your arm to your body, it will cause isolated areas to absorb the majority of the force and will make that area sore. If you aren't wearing wraps that might be helpful too. I'm sure Ryan and some of the other instructors here on the board could provide a lot more accurate and helpful info. Good luck!
Also, Chris may have something pre-existing, like tennis elbow or carpal tunnel syndrome.
Chris, do you wear handwraps under your gloves? I'm not a big fan of them myself, but probably would sport them if I felt chronic lower-arm pain.
