I was told before that they "think" that I have ulcerative colitis. I was put on medication. But after it stopped helping, I stopped taking it, and I was fine. Then just recently I have been feeling horrible. Stomach pain, mostly on the right lower region, gas, bloating, nausea, fatigue, and sometimes stabbing pain in my right lower abdomen. I am not pregnant ( that I know of, I have an IUD) And this has been going on for 3 weeks, non stop.
