Hi Sandy and Snoopy, thanks for responding. The culture came back showing normal flora. But I'm still having some symptoms. Weird....just waiting for the nurse to call back as to what to do. My abdomen and back are feeling kind of achy too. Ergh. The aching isn't high up (flank pain)--I know what that is since I had kidney stones 2 years ago--so I don't think it's higher up? or kidney infection? I just wonder if I can have Tysabri on Mon. as well.
