I am at the end of my rope with this issue ! About four months ago my vagina started burning internally , I immediately called the doctor and assumed I had a yeast infection I was prescribed Diflucan and nothing changed. Convinced I had an STD I was tested by my primary for Gonorrhea and Chlamydia as well as well as a BV test . Everything came back negative but I was prescribed Metronidazole. Symptoms began to clear up and came back a week later. Recently the pain started to drive me crazy, itching, burning, slight discharge so I went to my Gyno (twice) Both times she said I was "irritated" internally and had slight internal bleeding in my cervix which she froze for me. I was given Terconazole which did not work and I was tested again for Gonorrhea, Chlamydia, and this time trich, BV, and yeast. EVERYTHING came back negative! Finally my doc suggested perhaps my PH was off... I tried RePHresh, eating yogurt and acidophiles. NOTHING works. I am in a monogamous relationship with someone who has been tested twice as well. For a while we were using condoms and my symptoms seemed to improve a bit, but it killed our sex life. I read that sperm has a high PH? I have searched everywhere on the internet for causes and treatments, my doctor is starting to think I am a hypochondriac and I am driving my boyfriend CRAZY but this irritation is really driving me to the edge, I am honestly miserable. PLEASE HELP
