Wow! Someone else that seemed to have gotten IBS after going through UTI and multiple prescriptions to treat it! I don't know of there's a direct link, but let me know what prescriptions you had and I'll look into it. I also went through all that shortly before I was diagnosed with all this, but I do suspect I had the IBS condition all my life, but never really had it bad until this last year. I tend to think it's more stress related and I was under a lot of stress this last year so for now I'm looking at that at the main cause.
Please email me what you took for antibiotics- it might turn out to be another possibility.
