Ok the past 2 days I had really bad constipation were I had constant vomiting and throbbing lower abdomen gas pain, I got really swollen so I went the ER and after xrays they said its fecal retention. The same night I drank water with salted magnesium and it did stop the pain but next morning still constipated with more swelling. Then I drank plenty of prune juice and that did help, and I did had diarrhea from the magnesium. Even though I feel i'm not constipated anymore I still feel a little heavy and swollen with my right side pain like I'm recovering from surgery is this normal?
