I have had ibs for 8 years. A year ago i had an episode of what i thought was ibs, i had severe stomach pain, diarrohea and lots of rectal bleeding, went to g-docs and was told it was just ibs. Had another similar episode a month later, my doc sent me to hospital for tests. I had a sigmoid colonscopy, scans etc, surgeon said i have beginnings of diverticular disease and scheduled me for barium enema, the results came back clear, which i cant understand. Went to doc several more times to be told i have ibs not diverticular disease. I am now having these episodes on a weekly basis, severe stomach pain, constipation, diarrohea, fever, headaches, some rectal bleeding and vomiting with pain that bad i feel like im going to pass out. Doc never gives me anything but painkillers which just constipate me.Have been to doc countless times , then to be told i dont have ibs i have diverticular disease. Had another episode 2 days ago, went to doc again to be told that i have ibs and diverticular disease, i dont know if im coming or going. Hopefully someone can throw some light on the subject for me.
