I had a bad bout of LH trigger thumb a few years ago, doctors wanted to do surgery. Naturally, I didn’t want that if it could be helped. A guitarist friend had had other similar joint issues and said turmeric pills had helped…
I tried them, couple of months (takes a while for relief to work) and lo and behold, total cure!
Best thing was, not expensive, and zero side effects, unlike a lot of pharmaceutical treatments. Give it a try, it can’t hurt, at least…
