For a long time, I've been worried about my thumb. I asked a doctor briefly what he thought, but it was late so he just looked over it quickly and said there wasn't much he could do (which is fair enough as he had another patient to see).

Basically, to me it looks like my thumb's dislocated, but it isn't because it's not painful enough to be that. My left thumb is fine, but on my right one you can see some of the bone from what I'm guessing is the socket poking against the skin. Occasionally it gets sore and clicks a lot if it pops, after cracking my knuckles (which I don't do often).

I'm worried because I heard that it could be arthritis, but I play the guitar and am only eighteen, so is there much that can be done about it if it is that. And what do you think that it is?


Thanks! x
