Itchy vagina with burn but no odor or discharge?

It depends: Probably the most common cause is a yeast (or candida) infection, particularly if a woman has taken antibiotics or birth control pills. An allergy or other reaction to soaps, spermicides, scented pads, or lubricants is also possible. Occasionally, a herpes infection can cause intense itching and burning. In older women, low estrogen or irritation from urine leakage are possible. See your gyn!
