Hi there, evabella. So glad that you posted!I think that I had leanings towards IBS as a kid, but I have an idea that antibiotics (yes, for acne) triggered everything off.Many moons ago, after having been prescribed anitbiotics, I was sitting in a crowded lecture room when I felt this rumbling sensation in my anal area which I could not control, and I ended up clenching my butt cheeks for the rest of the class. I was in the same situation - the same time and room - the next day, and you know the story, history repeated itself. It was downhill from there, and gradually I got those sensations right throughout the day. I also developed very much changed bowel habits, namely having a bm as often as possible, not because I had to, but because I wanted to try to make myself 'empty.I think that stress was also a factor.And, you know what, the antibiotics were a waste of time. I had bad acne for a couple of years after. I don't know what stopped me from becoming a social hermit. Farting and acne to contend with at the same time. They were challenging years.
