I was "blessed" with the gift of haveing all my fingers on both hands and the thumb on my right hand being double jointed. I thought this was a gift until I started playing guitar. Now my problem is my pinky on my fret hand, anytime I use it for exesive amounts it locks up and it is quite weak, even though i have been grip exercising and playing with it more than i normally did for the last few months. Is there any known cure for this??? anything i could do medically to get rid of the problem, anything at all, i would appreciate the help.

Thank You
