I agree, you need to see a good Gastro doc. Often we can become impacted with stool which won't move and other stool stays in liquid form going around the impaction coming out as diarrhea, all of this can cause the type of pain you are describing. What did they suggest that you take to loosen up the stool? Call a Gastroenterologist to make an appt. and ask what you can be doing in the meantime to get things moving. A cyst on your ovary would not cause these symptoms and normally go away on their own. Magnesium citrate is good for getting things moving as well as Miralax. Best wishes.
Your pancreas is on the left side, not the right. right side pain is usually gallbladder or appendix.
To really look at your gallbladder, they need to do a HIDA scan, which they probably aren't going to do in an ER. You should go to a good gastroenterologist for a full work up.
I am concerned that you had diarrhea but ct scan showed you are impacted. You may have a partial bowel obstruction, which could be very serious. Again, a gastroenterologist can do a full work up and figure out what is wrong
