I've suffered called hands, fingers and wrists which in turn has made them sore, right up my forearms. I tried gloves and stuff - part of it might be that my home office is in the basement and I live in a climate that sees -30C.
Anyways, my fix is to get the heart rate up. I jump on the treadmill at an incline and do some push-ups. 10 minutes is all I need. And no, I'm not a fitness freak.
