Hi, Groovygirl (neat name!),
Welcome to the chronic pain forum of Healing Well. I don't know anything about PVNS, but hopefully someone will come along who does. I do understand pain and surgery, though.
This is a great group for support, although we're not doctors. You mght try searching the old threads and see if there's any information on PVNS.
Wish I could help more. Again, welcome.
