Hi i have been having poblems with my vaginal area for a few years now. i get excessive itching and burning, sometimes a discharge sometimes none at all. i have taken thrush tablets before and cream but my skin went white and inflamed and felt worse, a dr told me to use nilstat intead of other creams. thrush tests dont come back positive for thrush? i have had std checks and they have come back as nothing. i have herpes swabs that have come back as nothing but i have'nt had a lesion to swab. recently i noticed a lump on my outer vaginal lip that looks like an inflmed pimple? its not really itchy but i have had discomfort when i touch it?? how do i know if i have herpes? where can i get a blood test??? please help!!!
