Do I have a yeast infection or something else?

Go to WEB MD site online and input symptoms if you can...begin with the cough because i was just looking into a sore throat/cough situation I am having and I remember reading something about those symptoms being linked with stds....also a yeast infection is very very itchy and the scratching is what causes your skin to swell up down there...if you still have doubts go back to your doctor and have them check you down there too.
