Woke up at 2:30 last night with left arm aching, so used tens unit on my neck, then went back to sleep woke up not hurting, everything came out of me quickly. So Imodium, it was that ended it for the day. Seem to be ok tonight after another treatment. Hopefully, won't have same problem in morning. And, will sleep all night. I am hoping will not have pain. I have never been that thrilled about this all this treatment, though everyone keeps telling me I need to do. After being in pain from mid-May till end of August before hysterectomy I just do not want to go back to pain. Am hoping this can go as smoothly as possible.
