Hi all - first time here! I've had IBS for years but over the last couple of years have had periodic pain in the upper right abdomen area. Comes and goes - sometimes I don't have an attack for months. When it comes on it's constant, responds to heat, and I have to take painkillers. Can last a dayor so. Have had a gallbladder ultrasound and general abdominal scan, and all came up negative. With the pain I get tightness down my right side. I am wondering if this is just another manifestation of my IBS? My doc wants to get a colonoscopy done (oh joy!) but says she wouldn't be surprised if it is 'just' IBS. By the way, antispasmodics (Merbentyl) don't help!Any ideas?
