@CritterKeeper My doctor was about to schedule me for surgery when I read about how trigger finger can be caused by a vitamin deficiency. Supplementing with P-5-P (a healthy form of B-6) can make the problem go away. I called my doctor and asked him to hold off on the surgery while I tried the P5P.
I had it in my thumb and, after taking the first capsule, it never locked again. The pain subsided and my thumb straightened. I got full range of motion back. No pain.
