question: Hi i had an ear infection and sinus infection last week. I was taking predinome and sulfemothaxozole or something like that. I was getting better but then I had a bad cough one day and swollen glands etc. then I got a 102 fever in the middle of the night . I went to the dr. And it is not strep but she switched my medication to z-pack. I now have abdominal pain and green stool.. Any ideas ?
