I was tested for Chlamydia which came back positive, My doctor gave me the one dose of Azithromycin . Its been a two weeks since I took the pills, and I'm having loose stools which it hasn't stop since I took the pose. Also I have a burning sensation on my vagina when I pee. About a week ago I had some white little dots on my vagina which have dissapear. My doctor says I have a UTI. But im still worried that It may be something else. Should I be tested for something else? or are these common side effects?
