What is the cause of irritation and pain in the vagina?

Sometimes I feel irritation in the vagina. It's kind of a sweet pain. But it puts me off from sexual pleasure or any other activity. How can I get rid of this? I have tried applying mustard oil, which works. But I want a proper treatment. It recurs every 3-4 months. Please advise.
