I too have the same thing. The pain under both sides of my ribs started about six weeks after surgery. It sometimes radiates to my back muscles, especially on the left side if I’ve been standing too long or sitting in the wrong position. I recently had a colonoscopy/endoscopy, which revealed a possible allergy to wheat gluten. I have been on a wheat-free diet for about three weeks, and it hasn’t helped at all. My blood work and liver enzymes were all normal. I don’t know what is causing the pain, and it really worries me. I never had stones, just a low ejection fraction, so they took my GB out. The surgeon said that it was inflamed and was surrounded by scar tissue. Could I now have fibromyalgia? I’ve also noticed that since surgery, my rib cage has expanded by about an inch (bra size is larger). Has anyone else noticed this?
