What can cause severe upper and mid right quadrant pain?

I have been experiencing severe abdominal pain for the last 3 days to the point of being intolerable at times. It is in the mid and upper right quadrant. I do not have nausea, vomiting, constipation or urinary symptoms. I have had a laproscopic gallbladder removal, total hysterectomy and appendectomy. After my gallbladder was removed, I had to have an ERCP because a gallstone lodged in my common bile duct (1989). I have an appointment with a gastroenterologist next Wednesday, but I am not sure I can tolerate this pain that long. I am on Ultram 100mg every 6 hours, which does not resolve my pain.
