Genital sores - female

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:

• Genital herpes -- small, painful blisters filled with clear or straw-colored fluid
• Genital warts -- flesh-colored spots that are raised or flat, and may look like the top of a cauliflower
• Chancroid -- a small bump in the genitals, which becomes an ulcer within a day of its appearance
• Syphilis -- small, painless open sore or ulcer (called a chancre) on the genitals
• Granuloma inguinale -- small, beefy-red bumps appear on the genitals or around the anus
• Lymphogranuloma venereum -- small painless sore on the genitals

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 red 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)
• Cysts or abscesses of the Bartholin or other glands
• Trauma or scratches
• Flu-type viruses that can cause genital sores or ulcers in some cases
• Inflammation of the hair follicles (folliculitis)
• Molluscum contagiosum

See a health care provider before treating yourself. Self-treatment may make it harder for your 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 tested and treated as well. Do not have any type of sexual activity until your provider says the sores can no longer be spread to others.

Contact your provider if you:

• Find any unexplained genital sore
• Have a change in a genital sore
• Have genital itching that does not go away with home care
• Think you might have a sexually transmitted infection
• Have pelvic pain, fever, vaginal bleeding, or other new symptoms as well as genital sores

Your provider will perform a physical examination. This most often includes a pelvic examination. You will be asked about your symptoms and medical history. Questions may include:

• What does the sore look like? Where is it located?
• When did you first notice it?
• Do you have more than one sore?
• Does it hurt or itch? Has it grown bigger?
• Have you ever had one before?
• How often do you have sexual activity?
• Do you have painful urination or pain during sexual intercourse?
• Do you have abnormal vaginal drainage?
• Has a partner tested positive for an STD or noted similar sores?
• Have you shaved or waxed recently?

The following tests may be done:

• Complete blood count (CBC)
• Blood differential
• Skin or mucosal biopsy
• Vaginal or cervical culture
• Microscopic vaginal secretion exam (wet mount)

Treatment may include medicines that you put on the skin or take by mouth. The type of medicine depends on the cause.
