I haven't started my period yet, and I have constant itching in my female region. I have told my mom, I've been to the doctors 5 times. Tested 2 times for UTI, STD,yeast and bacterial infection, all negative. It all started with pinworms in my back side last year. I went to the doctor and she gave me medicine. The thing is, whenever the pinworms got really bad one night.....my front side started itching also. That was a while ago though. But I still have constant itching. I'm so depressed I hate everything and I really really need help. Is it possible for pinworms to cause the same feeling as a yeast infection? And if it is pinworms....will regular over-the-counter pinworm medicine work? Thanks.
