Sores or lesions on the female genitalia or in the vagina may occur for many reasons.
Sores on the female genitals
Genital sores may be painful or itchy, or may produce no symptoms. Other symptoms that may be present include pain when you urinate or painful sexual intercourse. Depending on the cause, a discharge from the vagina may be present.
Infections spread through sexual contact can cause these sores:
Changes that may lead to cancer of the vulva (vulvar dysplasia) may appear as white, red, or brown patches on the vulva. These areas may itch. Skin cancers such as melanoma and basal cell and squamous cell carcinomas may also be found, but are less common.
Other common causes of genital sores include:
Long-term (chronic) skin disorder that involves scaly and itchy rashes. (Atopic dermatitis)
Skin that becomes red, sore, or inflamed after contact with perfumes, detergents, fabric softeners, feminine sprays, ointments, creams, douches. (Contact dermatitis)
See a health care provider before treating yourself. Self-treatment may make it harder for the health care provider to find the source of the problem.
A sitz bath may help relieve itching and crusting.
If the sores are caused by a sexually transmitted infection, your sexual partner may need to be treated as well. Do not have any type of sexual activity until your health care provider says the sores can no longer be spread to others.
