Hi, I am 37 yrs old. I am getting over an ER visit 1/1/14. My symptoms were debilitating with screaming pains in the upper stomach that felt like burning or stabbing. I couldn t walk or stand, became severely fatigued, weak dizzy, bloatness and severe loss of appetite. I was told that I had diverticulitis and given 2 antibiotics and pain meds, however, when my GI doctor got my ER recs, I didn t have it, but looked like I had colitis instead. I also take Amitiza every couple to few days to have a BM since I have a history of maybe going every 4-5 days. I also have had the Mirena 7.5 months and have endometriosis as well. Could these 2 things be causing my pain? Please help!
