Vulvovaginitis: May cause burning and itching of the vagina and should be treatable with a variety of creams and anti-irritant measures. However is important to see a doctor for examination as there are a variety of other skin conditions and infections that can present like this that may need to be excluded.

Yeast?: Sounds like a yeast infection. See a doctor or clinic for diagnosis and recommended treatment.
