Vaginal itching may be something as simple as a vaginal yeast infection. If you suspect a vaginal yeast infection, and it's your first one, check in with your care provider. Treatment for yeast infections is simple with antifungal creams such as Monistat. If you're having problems getting rid of your yeast infection, check in with your care provider. It's also possible to pass yeast infections to a sexual partner, so your partner may need treatment for a yeast infection too. Ways to prevent yeast infections include wearing cotton underwear, avoiding tight clothing, eating yogurt with live cultures, and decreasing sugar consumption, especially if you have diabetes.
