I just had surgery in Oct. to clean up adhesions. My IBS has been in serious flare up since early summer. My GI thnks it is damage done to the outside of the bowels by the adhesions. I was messed up pretty bad inside. Currently seeing a urologist, my left ureter was damaged. They put in a stent to hopefully save the kidney. Check out other posts for my whole nightmare. I had trouble getting doctors to believe me when tests showed nothing wrong. Thank God some did. I had problems that could've proved life-threatening.
