I have severe abdominal pain after a bowel movement. The pain can last for hours. I have been taking Tramadol. I aways use a heating pad. Sometimes I can get relief, but not always. Once the pain is gone I feel good, until the next bowel movement. I am in kidney rejection after a 10 year transplant. Have so many medical issues due to kidney. The Dr says this is not kidney related. Most days are unbearable and I hardly leave my home. Your suggestions are appreciated.
