Umm, hi. I've had an IBS dx for 4-5 years and recently am being re-evaluted to be sure there is not anything else going on GI wise. I have been reading some books from library etc. One book states that IBS does not cause pain at night? I don't usually have pain at night but did during my recent "flare-up". What is your experience? Do you have pain at night from your IBS? Also, does anyone know of any research or sources that agree with this statement that I could take to my GI doc? Any information appreciated. thanks.
