hi get yourself off to an std/gum clinic the staff will be really helpful to your problem if its a yeast infection that's gone wrong or an std they will tell you can get you on the right meds for your problem. this will help you. good luck
what other than a yeast infection could it be if the medicine doesn't work and more symptoms start occuring? . for a few months now i've had constant vaginal itching and burning and after using yeast infection medicine multiple times it still has not gone away and now blisters have begun forming. after looking up genital herpes i've noticed that i have nearly all the symptoms for it but i have yet to have sexual activity. could it still be possible or is it something else?
