Hi Compart1 and John of MT, Thanks for the advice. I've started stretching and I think it's going to help a bit. I've also been to see physical therapist. He says the main problem is that, as a tendon from my index finger was used to attach to the snapped tendon in my thumb, my thumb now works at an unusual angle. Not much I can do about that really. I think,as JeffS65 suggested, I should think my way around the problem and let it become my style a la Django Reinhardt.
