Mine is basal joint arthritis. It's the most common arthritis in the hand. Nothing much can be done. I wear a brace, which helps a little, and ice often after playing.

After reading this I played a bit and observed myself. My thumb is all over the place. It jumps around for different chord shapes and runs. It can do that because it doesn't support the neck much. I bet there's a pretty good difference between having the strap attached at the tuners rather than at the scroll. Much of the pressure by my thumb is against the pull of the strap which is enough to fret the notes. There's also the issue of my belly. I'm now thinking of considering it a bit a of an asset as it helps hold the instrument in place.
