I was diagnosed with trichomoniasis last year around September. Ever since then, I have been having vaginal itching on and off. I went back to the doctor and they saId that it was a yeast infection. The itching stopped for about a couple of months and came back. I went to the doctor again and they said that there was nothing wrong. I recently went back to the doctor because I was experiencing vaginal itching in the vagina and vulva area. It was also burning. They said that I had a yeast infection and bacterial infection. Now I still feel itching in the vagina ( it feels like it is by the cervix, sometimes its like a throbbing itch, i really dont know how to describe it) and a little pain and itching in the vulva area sometimes. I have gone to the doctor about 3 days ago and they said that nothing was wrong. I was having a discharge at first but the discharge has gone. I am tired of the problem and i have been having pain during intercourse. What could it possibly be?
