Vaginal infection: You could have a yeast infection, vaginosis or std. See a doctor.

Vaginitis: Sounds like you have an infection/inflammation on your vagina. It could be bacterial, or fungal or could be contact dermatitis from tampon etc for instance. If you are sexually active- std should be ruled out. You should go to see your doctor/gynecologist and get checked. Pelvic exam, swab and cultures would likely be needed. Vagisil only works for yeast infection, but not bacterial infection.
