Best advice for anyone is "go see a doctor." I've had arthritis in my hands and fingers for years (I'm 71). Tried the non-meat diet eating only salads, kale, salmon and it did nothing for the arthritis, but I sure did lose weight. I finally went to a specialist, x-rays were taken other diagnostic procedures were performed, and he diagnosed exercise, primarily exercise balls. So I started every AM, while drinking coffee and watching TV squeezing balls, and within a few weeks, I could flex my fingers, move my hands just like I did years before. Even to this day, I start every AM with the exercise balls and I have had NO problem shooting anything, including my .44 mag lightweight revolver. First of all, you need to see a specialist to find out exactly what the problem is and go from there to decide what to do.
