Since I have not been officialy diagnosed after basic tests including colonoscopy(?)I need to know if I have IBS. My symptoms are that every couple of months I have for about a week these symptoms: loose bowel movements, not often, maybe once a day only, but the movement will be diahrea like, and during the day I have occasional cramps and general discomfort, and of course life is less enjoyable as I worry all the time about 'having to run for it'. Then it will dissapear and return after some months and last for a week or two.IBS I only heard of in the internet and it sounds like I have it.thanks for any input.LB
