Okay I've had yellow discahrge and burning since last July. I've been tested for STI's all were negative. Well last Friday my girlfriend took me to the hospital because of the burning and the pain the hospital tested for trich yeast gonherra and chlymidia. They said it was all negative and sent me home. Well I went to my gyno Tuesday and she checked me for yeast and said I had a horrible yeast infection that I had to have for months. But I've taken Diflucan many times and it didn't go away well she gave me three doses of Diflucan and a vaginal suppository with a weeks dose. I've taken it all and it refuses to go away. Can any one help? What's wrong with me? She also retested me for the stds gonherra and chlamydia, but I know that it can't be this bc I have taken zithromax tons of times for sinus infections which this antibiotic is used to treat these stds. Please please help I'm tired of suffering.
