I've never really had issues with my hands or fingers until I started training in the gi. I've been in the gi now, for about 4 or 5 months. In the past month or so, when I awake in the mornings, my index, middle, and ring fingers hurt, on both hands. I can straighten them out just fine, but making a fist is what hurts. I force myself to make a fist, to try and work it out. Is this a common thing with gi training or do I need to accept the fact that I'm getting old. :P Im only 31, by the way.
