I had to have serious hand surgery last Thanksgiving. Ligaments blown right off the bones on my thumb (karate incident) and they were retracting so time was of the essence.
If it was not done quickly they would have to cut out other parts of the body to use as the bungee cord because the old one rolled up.
So I hope your situation is not like that but there was no pickin' and choosing of dates in my case.
Anyway my casting hand was strong for the spring clave and I've hung up karate to pursue my interrupted guitar playing interests. Luckily the surgery has restored the hand structurally and I can strum away comfortably. Neighbors might wish I hadn't but thats another story!
