I'm having pain behind right chest area, upper and mid right back and shoulder as well as liver area for 3wks. 3wks ago it began and I was also throwing up bile. I was diagnosed with biliary colic, put on tylenol and bentyl. It is happening after I eat or drink (non fatty) foods and also for no reason at all. I am 37, and 115 pounds, 5 feet 6 inches and eat mostly a vegan diet anyway. Was seen by a dr and they also did an ultrasound. It showed no stones, only a gallbladder polyp and a few simple cysts in my liver. The polyps and cysts were not there in 2009. I was told they were not causing this pain/problem. And now they aren't sure it is biliary colic because of the length this has been happening. What should my next step be since I am still not right? One dr suggested a HIDA scan, and another said wait it out since the HIDA has radiation. I had quite a few xrays this past yr for other causes not related. Do you think a small polyp or small cysts can cause pain?
