I ve been having RUQ for 8mos. My GI doc says I m fine (normal US, normal blood tests, Hida scan BGEF 88%, endoscopy showed no ulcers , biopsies normal). I ve pretty much given up and just live with the pain (the symptoms read like a poorly functioning gallbladder ), but last night I had a glass of red wine (cut with water) and the pain was double or triple what it usually is. What would cause that?
