I am having severe left sided flank pain. Had a total hysterectomy, ovaries removed, bladder sling with mesh, hernia repair and lipoma removed on that side Oct 2013. About 6 months ago I began having this pain and it s only getting worse. I do suffer from constipation because I have to take pain meds for complex regional pain syndrome and migraines. I take all kinds of meds to have a bowel movement and even when I have one the pain is still there. I have a colonoscopy scheduled for August 26th but I don t think I can wait that long. No one is concerned but me, the pain is unbearable at times and even goes down my left leg and feels like inside my left buttock. Achey, sharp, and radiates to my back, I m also nauseated and can t eat but a couple of bites of food at one time.
