Within 10 minutes of having a bowel movement, my stomach blows up to an enormous extent, is hard, and extremely painful. I suffer from constipation, take meds to relieve constipation but this still does not eradicate the pain. The problem has become a DAILY NIGHTMARE. There is scarcely a day that I am not in debilitating pain. Have had a colonoscopy - all clear. Docs are clueless!
