I would suggest talking to your Dr.....it typically is what we are doing that causes the symptoms post op....
Are you still on any meds? I had a lot of muscle spasms post op and I took valium when needed to help with it....
BTW- what is hand spinning?
I would just be sitting and watching a movie. Or walking to the mailbox to get mail. It is very sporadic when it happens. I also just woke up this morning with such tight muscles on my left side that it feels like a charley horse all over.
May I ask what you are doing prior to this new symptom?
