I was concerned when I didn't see immediate improvement on only the turmeric pills, but my buddy who recommended them said it was going to take a while... One of the keys to recuperation on a thing like this (an inflamed tendon) is immobilization and as little use as possible. Sleep in that hand splint, basically, try to even play in it if at all possible.

I hope that you continue the turmeric, and show a bit of patience before you get to the surgery option. After all, I bet your doctor was pretty optimistic about the injection route, too... but that doesn't seem so far to have panned out for him. What guarantees is he giving that surgery will permanently cure it and impart NO loss of function of the thumb? Me, I was scared sh**less of that possibility, and gave the turmeric FAR more time than I would have were it another joint in my body!

Fingers (and thumb) crossed!
