In hospital over the weekend b/c of gallstone attack

I was in horrible pain over the weekend and went to an urgent care clinic as soon as they opened Friday morning. They wanted me to go to the hospital b/c they were afraid it might be my appendix... anyway it wasn't my appendix. They did a cat scan and saw gallstones. After giving me a few doses of morphine i was feeling better... then they said I could go home. I'm still not feeling great. I stomach is sore.

I'm not sure what to do now. I'm supposed to go to a specialist this week. If I do the flush does it causes you to pass the gallstones? It was horrible pain I really want to avoid further pain.

Thanks!
