The past couple of weeks I have had an aching pain in the middle knuckle on my right middle finger. I taped it up, no problem. Yesterday after shooting for about an hour, the pain was back again so ... 2 + 2 = I realized that somehow the knuckle was taking the brunt of the camera's weight. So.. Am I falling apart, or is this somewhat common? Edit: I use Canon XTi, if that matters.
