Hello all. I am, almost certain, Lactose Intolerant. I was allergic to milk as an infant, and never drank milk growing up. I can tolerate milk in the mornings *with coffee and sometimes with cereal* but as of lately not at all! So, about 3 days ago, we ate a meal that contained milke (bechemel sauce to be exact) I am still having D. And the time before that was some 3 weeks ago in europe when i had ice cream and it sent me into a 3 day D attack.Do you think that I have some sort of infection? or is this IBS? Or is this Lactose intolerance??? Any help is appreciated!
