Recently I had been having some itching and discharge so I went to the Dr. I was given medication for a yeast infection. The itching continued. I went to the dr. again and she saw a small open sore near my anal area. I took a hsv 1 and 2(blood and a culture were taken), gonarreha and syphilis and all came back negative. I am now having itching(every now and then) on and around my labia major which produces little cuts underneath or around. Can some one tell me what wrong? I am so confused and need an answer.

I'm also scared it my be herpes because I've been reading on the internet that the test can come back negative but you can really have it. ?
