I had severe constipation with build of in my upper intestines of hard stool that would not pass. It showed in xray. Just went to ugent aid cause i couldnt eat and was bloated and could no poop after normal stool softeners and prune juice. Dr. There said i had lots of stool built up to go get an enema. T Because I couldn t give myself an enema I came home and I cleaned myself out with liquid magnesium feeling it s like a fizzy drink you drink before you get a colonoscopy. And they cleaned me out and now my stools are yellow like really mustard yellow and I m concerned about that should I be?
