Re: Is this I.B.S
It doesn't sound like the classic symptoms associated with IBS. I've had it for several years and IBS attacks can happen anytime, but in stress situations they tend to come on more often. I have had them happen a lot after meals and also at work, where I was in a high stress job.
I would say to see your PCP and ask him/her to refer you to a good Gastroenterologist and ask him/her to do a complete workup on you. I had every test they do for this type of problem, including a Colonoscopy and Barrium Follow Through, and it was only after complete testing they said it was IBS. I am on Social Security Disability due to this and some other medical conditions.
Good luck to you.
