I have advanced rheumatoid arthritis and have been having alot of pain in my bowels. The anti-inflammatory drugs caused alot of pain and I am off them but I am still in horrible pain. When I passed the last stool, even though it was soft I it still felt like I had knives in my lower bowel. I at times been bleeding when I pass stool lately. I've had fevers and nausea, but I thought that was from the arthritis and the medication I am on. Help!
