I posted on this site last week to ask about picolax. I hope you don't mind but I thought some of you may have had this problem. I was given barium by way of an enema before having a defecating proctogram on Monday. During the test i was unable to expel any barium whatsoever. The radiologist said he could see that some of the muscles at the bottom of the colon weren't working correctly. Now, I still have the barium retained, I'm unable to have a BM, have took Movocol to try to help, and i've got serious pains in my lower abdomen and pressure in my bottom. How can I get rid of this darn barium and will it be causing any problems still being there. Any help would be greatly appreciated.
