Hello Doc, I am a 28 yr old female ht - 167 cms, wt - 68 kgs. My problem is of an acrid vaginal discharge which is odorless and colorless but it causes a lot of itching, dryness and soreness. It has been happening since last 2-3 months, every year 1-2 attacks, disappears during the menses but reappears as soon as the cycle ends. Is it something serious?
