Long standing RUQ pain. One strange symptom is that the RUQ pain gets worse after a bowel movement. No GB. ERCP mild stenosis. Pain cont. Ideas?

Colon? Wonder if this could be related to your colon, as part of it is located in that area. Have you had a colonoscopy? Ask your primary care doctor or gastroenterologist to set this up for you. Also, I see you are on Cellcept (mycophenolate mofetil). Have you had a transplant? If so, be sure this isn't causing symptoms. Good luck!
