I've had that as well! In fact, I had to have one done twice because it froze - but we won't even discuss it because it just won't happen to you, now will it?!? Because you will be a good person and do all of your therapy and not over do things, right?
I do still knit English, though...... and it's fine, now that I've healed. Have you had your surgery? I do have a post surgery tip if you haven't. I also have a couple of the auto-immune arthritic diagnoses (FYI, once you get one, they stack, like potato chips, , but it's not necessarily a bad thing, it's the same you, just different paperwork, according to my husband)
Let me know if there's anything I can help you with, or just talk to about. I've been there.
