I am a 23-year-old female and have been having symptoms of gallbladder problems for the past month and a half. (Severe right upper quadrant pain, positive Murphy's sign, yellow diarrhea, nausea, and right shoulder pain). The attacks last anywhere from 20 minutes to several hours, especially after eating fatty foods, and even lean pork. I vomited once during an especially bad attack. I ended up having an ultrasound that showed no stones, a HIDA scan that came back normal (gallbladder functioning at 87%), and an upper endoscopy that showed no abnormalities. I have a family history of gallbladder disease. My grandfather on my dad's side, my half sister on my dad's side, and my mom have all had their gallbladders removed due to gallbladder disease. What else could this be? None of the tests I have had show conclusive evidence of gallbladder disease, but all of the signs and symptoms point to gallbladder. I don't know what to do and am sick of dealing with all of this pain! Please help.
