| | discomfort in my right thumb knuckle
I too have been experiencing discomfort in my right thumb knuckle for a few months now. I initially thought it was caused by using a mouse, but now I'm not so sure. It's very stiff and when I extend it, the knuckle "pops" or sometimes "snaps into an extended position. When I retract it to a folded or curled position, it again snaps. After the snapped "detent", it moves smoothly. It's weird. But yesterday, I was painting a porch holding a brush and it seemed to feel much better and moved more smoothly. However this morning when I woke up, it was stiff and "stuck". I couldn't get it to extend fully untill after I was awake for about a half hour. Can tape or a splint help? Should I see a hand specialists? Is this serious? I'm 56 and beginning to accept some aches, pains and tiredness, but this I think isn't parr for the course.
