Ginny, I'm sorry you are having such a rough time after the hysterectomy. I had one 5 yrs ago, and I had a very rough recovery. My ob-gyn thought everything was great, what's the problem? I used to use weights to help strengthen my arms, after the surgery I tried that while I was sitting down. I got so nauseous, I almost passed out. Everybody has diffferent reactions, I would also suggest you talk to your dr., hopefully you have one that understands re: FMS. I didn't know I had FMS when I had the surgery. I have very little strength in my arms/hands, but I use 2lb weights a couple of times a week. My left hand still shakes while I'm lifting, but I'm pigheaded er, stubborn, I keep trying. Check w/ the dr., you don't want to have more problems on top of what you are already enjoying.
I also have back issues, have since I was a teen. I wish you a speedy recovery, my friend.
God bless. Alice.
