Sorry you are dealing with those. I know how you feel.
I keep having them on my stomach under my left breast where I had pain since I had Shingles. I have also had a few left side back & waist where I had pain.
For some reason I have them near my shin/ankle on right leg & my feet.
It's different when you get a charlie horse in your calf you can walk off but where I have spasms I don't know how to move or stretch to make it stop.
