I'm so sorry you're so sick. I had the left shoulder done and it turned out very well. I didn't have a nerve block for that one and they only reason I'm getting it this time is they are sending me home the same day. The last time, I had the cold machine and didn't have much pain. I will have someone stay with me the first night, which I usually don't do and then I'm on my own. I do have friends if there is an emergency. Don't be sorry for me. I'm a very strong person and it's amazing how many things I can do. I'm like a handywoman and if I don't know how to do something I can improvise. I'm pretty self sufficient. I'll be fine. I just wrote that so maybe I could help someone else be prepared for this. Keep on going.
