Thanks guys ! I have been in a probiotic for about 2 weeks now , I just don't understand and I'm so worried I've developed a new disorder !!! May 2nd was the day I got REALLY SICK .but now I'm worried that was just a disorder developing and not just a stomach bug , I felt okay for a few days then a lot of heartburn belly burning feeling , then went away for about 1 week now back ?!?! What the heck ?!?!my son has had some diarrhea last few day & a tummy ache , but I don't see how I could get sick again so fast .
