The skin on the sides of my vulva sting/burn when they are touched. they also are slightly red. what's the problem?

Must be seen: This sounds like inflammation but the source is unknown. A visit to the GYN MD can confirm and determine why this problem exists and provide any necessary Rx.

Vulvodynia: If there are no skin changes or discoloration to suggest infection, I recommend avoiding very tight jeans, wear whie cotton underwear, only wash the vulva with plain water and avoid applying lotions,etc. Consult a gynecologist as needed.
