Infection? Yeast?: The most common cause of vaginal itching is yeast infection. However, yeast usually causes a little white discharge, or none at all; brown discharge is worrisome for a different kind of infection. Depending on age and sexual exposures, it could be an STD. Or a simple hormone problem. You can never know through a forum like this; see your doctor soon. Good luck!
