Infection...: This is most likely related to an infection. Based on your description seems to be a fungal(yeast) type especially if you are having itching associated as well. However, fungal infections do not usually present with pain so you might be having a bacterial infection also. See a gynecologist in order to get exam and tests as necessary.
