Town without pity ping.
Sorry but there are vast amounts of people who have been diagnosed (or maybe even misdiagnosed) with IBS.
My case in point, I was diagnosed with IBS and suffered for years.....until, while sitting in my internists' office waiting and waiting for my appointment, I came upon an article that was headlined with the same symptoms that I had suffered for years.
What was this "mystery illness" it was lactose intolerance!
Always ready to try some way to alleviate my symptoms as they had made my life miserable since age 5.
Having secretly torn out article (it was in an out-of-date mag.) I followed the directions and avoided all products that include some form of lactose (there are many.)
Within numbers of weeks, my symptoms disappeared. When I returned to my doctor, he inquired how I was doing and when I said, "fine" he was stunned. I told him what I had read and done and how I was now without those awful symptoms. He was very skeptic but you can't fault success.
Last comment on story of my experience with IBS, I had been searching family records for genealogy and received both my father's and grandfather's veteran records from the National Archives. They were both released from military for "dysentery." Lactose intolerance obviously runs in the family!
