Gary,
I'm sorry to hear about your fingers. Hopefully in time, the medicine prescribed will work and you'll be healed.
I'll get a 2nd opinion for you (wife is a nurse and works for 4 doctors) to determine if there's anything else you can do.
You're an inspiration to me. Thanks for your tutoring (for all of us) and contributions to the PSR forum.
Hang in there. I'll be thinking of you.
And don't type for a while
