Had a bad pain in my upper abdomen a few weeks ago. Went to urgent care, but they were no help. Went to gastro doc and he did a pipida scan and a stomach ultra sound. Seems my gallbladder is not working properly and I have gallstones. Went to surgeon yesterday but he wants a MRCP done first to see if there are any gallstones in the bile duct. And if there are, he wants to do an ERCP. Anyone had these tests before?
