It is just not right that so much pain should bedevil you. Your stim surgery is pretty recent, yes? What an awful predicament! Since my stim was not officially made operational for a couple of weeks after permanent implant, I had to control pain with the pain meds my physiatrist prescribed. I did walk, did lie down, did move carefully. Lay on my side and put a pillow between the knees. Applied cold packs to the incisions. Among my pills was flexeril, a muscle relaxer for the possibility of spasm, and as they occurred due to the disturbance of some muscle tissue, I did use them sparingly.
I pray that your spasms will abate, and soon!!!
CARING,
