5 years ago I had a colonoscopy and had a benign polyp removed. Last fall I had another colonoscopy and had a very small benign polyp removed but showed an otherwise healthy colon. This February(about 5 months after my last colonoscopy) I was under the most tremendous stress of my lifeand experienced 2 days of diarrhea(twice a day) followed by a day of constipation with one hard stool with white mucous, followed byanother week of once a day diarhea with mucous. For the past 4 months Ive experience different stools(usually smaller, looser but not diarhea) have had diarhea about once a week and have had noticeably more gassyness. I must point out that I dont feel pain but seem to feel the gas moving through me, feel gas near my left rib,and feel my intestines contracting(both lower and mid abdomen) but not really pain.I rarely have a normal stool, usually dark now(they were light for 2 weeks after my first episode)but sometime they initially float before sinking(gas?) and are just different.Does this sound like IBS?Does everyone have pain?Can IBS cause stools to be different every day than they were before you had IBS(rarely a normal stool)Is it strange that these symptoms appeared just months after a colonoscopy that showed anormal colon?Any replies greatly appreciated.
