I am positive my IBS-D started several months after my surgery. You did ring lots of bells with the infection thought. My incision wouldn't heal & finally after several attempts to cauterize, etc. he referred me to a plastic surgeon to have the incision redone. I went to that guy & the first thing he did was probe around inside & found a stitch that hadn't dissolved. Within several days it was healed. I started a new job about the same time the IBS started and blamed the condition on the job rather than the surg. But, I finally had to give it up about a year ago and the IBS didn't improve. Mine is of the worst kind with the urgency that I can't control or time or anything else. I've pooped my pants so often in public, at work, etc. that it really depresses me. I was always an out-going person but this tends to make one a recluse!At this point I don't know of anything that I can do, especially if I have gut nerve damage as yourself. The gyn who performed the surg. is now retired so I don't even see him anymore. Thanks for your input. Is there any meds you can take for the nerve damage or is it something you've learned to live with as I have.Misty
