Sorry about your arm/hand! I've had that kind of stuff - the MRI usually just says, yep, it's messed up. :roll:
You were dealing with a sore on Buddy, right? I've been treating Kitty for something similar the last few days. It got a lot better when I used saline spray on a sterile pad to clean it, then put on the Neosporin pain relief. The saline made a difference. Thought I'd pass it along. Not sure how you would do this with one arm out of service, though!
Feel better.
