question: I have been having pain (most of the time it's dull and achy, sometimes it's sharp, lasting seconds to minutes) in the upper right quadrant of my belly (where the gallbladder is) since January 2010. I have been to my PCP, GI specialist, and ER a number of times. I've had a hida-scan, ultrasound, CAT scan, MRI, x-ray series, upper endoscopy, blood, urine, and stool tests. All came back normal (the upper endoscopy showed some acid reflux damage and a hiatal hernia). No one can seem to figure out what is causing the pain. Food, exercise, time of day, or anything else seems to be a trigger. I can still feel pain after taking Vicodin. It just comes and goes. What else can be done?
