To the person who posted and revived the post. Start packing in the probiotics. My daughter had this issue a year ago and probiotics took care of it totally. By the time they got around to calling with results and such she was better, got retested and we were clear. Never even had to take the meds they called to put her on. I insisted they retest since all her symptoms were gone already. Anywho we just flushed her system with probiotics and she was much better the next day and by 3 days after you would never have known she was sick at all. Really thats a good place to start whenever you have tummy issues. Everything on this farm get them. Horses, cows, goats, chickens, parrots, dogs, cats, children, parents and grandparents. Good stuff.
