Vulvar pain is any discomfort, burning, stinging, or soreness affecting the external genital area. It can be constant or intermittent, triggered by touch or seemingly unprovoked, and roughly 4% of women experience it in any given six-month period. The causes range from identifiable skin conditions and infections to chronic nerve-related pain with no visible explanation.
What the Vulva Includes
The vulva is the entire external genital area, not just one structure. It includes the outer and inner lips (labia majora and minora), the clitoris, the urethral opening, the vaginal opening, and several small glands. Pain can originate from any of these structures, and pinpointing the location helps determine the cause.
Vulvodynia: Pain Without a Clear Cause
When vulvar pain lasts three months or longer and no infection, skin disease, or other identifiable condition explains it, the diagnosis is typically vulvodynia. This isn’t a single disease but a label for chronic vulvar pain that persists after other causes have been ruled out.
Vulvodynia comes in two main patterns. Localized vestibulodynia is pain confined to the vestibule, the tissue immediately surrounding the vaginal opening, and is triggered by touch or pressure. Inserting a tampon, having sex, or even sitting for extended periods can set it off. Generalized vulvodynia, by contrast, is spontaneous, diffuse pain that can spread across the entire vulva and sometimes into the inner thighs and perineum. It doesn’t need a trigger to flare.
What Happens in the Nerves
Research on vulvodynia points to changes in how the nervous system processes sensation. Biopsies of vulvar tissue in affected women show increased branching of nerve endings, meaning there are simply more pain-sensing fibers packed into the tissue. On top of that, the central nervous system becomes “turned up,” a process called central sensitization. Nerve fibers that normally transmit only light touch begin behaving like pain fibers. The result: a cotton swab or gentle contact that should feel neutral registers as sharp pain. This combination of extra nerve endings and an amplified pain response helps explain why the area looks normal on examination yet hurts intensely.
Identifiable Causes of Vulvar Pain
Skin Conditions
Lichen sclerosus is one of the more common vulvar skin diseases. It causes porcelain-white patches that can wrap around the vulva and perianal area in a figure-of-eight pattern. The affected skin becomes thin, fragile, and prone to tearing, sometimes developing small blood blisters or fissures. Over time, the tissue can scar enough to shrink the labia minora, bury the clitoris under scar tissue, or narrow the vaginal opening. Symptoms include itching, soreness, and pain during sex or urination. Lichen planus is a related condition that can affect the same area, often producing raw, erosive patches inside the vaginal opening.
Contact dermatitis is another frequent culprit. The vulvar skin is thinner and more absorbent than skin elsewhere on the body, making it reactive to products that don’t bother you anywhere else. Common irritants include soap, bubble bath, scented laundry detergent, dryer sheets, synthetic underwear, panty liners, scented pads or tampons, talcum powder, douches, spermicides, tea tree oil, and even certain toilet papers or food preservatives. Switching to fragrance-free products and cotton underwear often reduces symptoms significantly.
Infections
Yeast infections, bacterial vaginosis, and herpes outbreaks can all cause acute vulvar pain, burning, or rawness. These are usually identifiable through lab testing and resolve with appropriate treatment, though recurrent infections can keep the tissue irritated and contribute to ongoing sensitivity.
Hormonal Changes
After menopause, declining estrogen levels thin the vulvar and vaginal tissue, reduce blood flow, and decrease natural lubrication. The result is dryness, burning, irritation, and pain during sex. This can also increase susceptibility to urinary tract infections and urinary urgency. Estrogen therapy, applied locally, restores tissue thickness, improves blood supply, normalizes vaginal pH, and relieves most of these symptoms. Hormonal vulvar pain isn’t limited to menopause; breastfeeding, certain birth control methods, and surgical removal of the ovaries can produce similar effects.
How Vulvar Pain Is Diagnosed
Diagnosis starts with a detailed history: where the pain is, when it started, what triggers it, and whether it’s constant or comes and goes. A visual exam checks for skin changes, discoloration, scarring, or signs of infection.
The most distinctive diagnostic tool is the cotton swab test. A moistened cotton swab is pressed gently against specific points around the vulva and vestibule. You’re asked to describe what you feel and rate the intensity. A strong pain response to light swab pressure, especially at the vestibule, points toward vestibulodynia. If the area looks entirely normal but the swab test provokes significant pain, that contrast is itself a clue that nerve-related changes are driving the problem.
Depending on findings, your provider may also take a swab for infection testing, order a biopsy of any suspicious skin patches, or check hormone levels.
Treatment Approaches
There is no single fix for chronic vulvar pain. Treatment almost always involves layering several approaches, and it can take weeks to months to find the right combination.
Topical Pain Relief
Numbing creams or ointments containing lidocaine are often the first step, applied to the painful area before sex or as a nightly routine. For nerve-related pain, compounded creams containing low doses of medications that calm overactive nerve signaling can be applied directly to the vulva. Steroid creams or ointments are used when an inflammatory skin condition like lichen sclerosus is the underlying cause.
Oral Medications
When topical treatment isn’t enough, oral medications originally developed for nerve pain or depression are commonly prescribed at lower doses. These work by dialing down the amplified pain signals in the nervous system rather than targeting the vulva directly. It typically takes several weeks for these medications to reach full effect, and dosing is increased gradually to minimize side effects.
Pelvic Floor Physical Therapy
Many women with chronic vulvar pain develop tightness or spasm in the pelvic floor muscles, either as a cause or a consequence of the pain. Pelvic floor physical therapy addresses this through internal and external tissue massage, trigger point release, stretching, and biofeedback training that teaches you to consciously relax those muscles. Electrical nerve stimulation (TENS) is sometimes used as well. This is one of the most consistently helpful treatments for vulvodynia, particularly when pain is provoked by pressure or penetration.
Reducing Irritant Exposure
Regardless of the underlying cause, minimizing contact with potential irritants protects already-sensitive tissue. That means switching to unscented soap (or washing with water only), wearing cotton underwear, avoiding fabric softeners and scented detergents, and choosing unbleached, fragrance-free menstrual products. These changes won’t cure nerve-related pain, but they remove one layer of aggravation from tissue that’s already on high alert.
Who Gets Vulvar Pain
Vulvar pain affects women across all age groups, from teenagers to women in their 70s and 80s. Survey data show the average age of women reporting chronic vulvar pain is around 50, but this likely reflects menopausal hormonal changes increasing prevalence in that group rather than younger women being unaffected. Localized vestibulodynia is particularly common in women of reproductive age, while hormonal vulvar pain clusters around menopause. Many women see multiple providers before receiving a correct diagnosis, partly because the vulva often looks normal on examination and partly because vulvar pain has historically received less clinical attention than it warrants.
