What could vaginal problems ( itching, burning..) be a sign for?

Infection: A vaginal infection can cause itching and burning with or without a discharge.

Chlamydia?: Is a very common sexually transmitted disease. Most people who have chlamydia have no symptoms. The major symptoms are pain or a burning sensation and "brown discharge". With the right treatment can be easily cured. Rec.: see your PCP for evaluation, tests, definitive diagnosis and treatment.
