For over a year now I have had severe abdominal pains, periods do make it worse. Have been to many ER's and Doctors. Have had ultrasounds, CT scans, x-rays, etc. All test finding nothing. Some have thought IBS, others endometriosis. Now they want to do a laprascopy. Dierria, and problems with food are obvious, but meds to treat IBS does not work. Any ideas.????
