Vaginal or vulvar pain has many possible causes, ranging from simple irritation to infections to chronic conditions. The good news is that most causes are treatable, and narrowing down your specific symptoms (where the pain is, what it feels like, and what triggers it) can point you toward the right answer.
Irritation From Everyday Products
One of the most common and overlooked causes of vulvar pain is contact irritation from products you use every day. Soap, bubble bath, laundry detergent, scented pads or tampons, synthetic underwear, douches, perfume, and even toilet paper can trigger a reaction called vulvar dermatitis. The skin in this area is thinner and more sensitive than skin elsewhere on your body, so it reacts to chemicals that might not bother you anywhere else.
Tea tree oil, spermicides, dryer sheets, and dyes are also common culprits. The pain usually feels like burning, stinging, or raw soreness on the outer skin, and it often comes with redness or swelling. If the discomfort started around the same time you switched products, that’s a strong clue. Switching to fragrance-free, dye-free versions of your soap, detergent, and menstrual products and wearing cotton underwear is often enough to resolve it within a few days.
Yeast Infections and Bacterial Vaginosis
These two infections are the most frequent causes of vaginal discomfort, and telling them apart matters because they’re treated differently. A yeast infection typically causes thick, white, odorless discharge along with intense itching, burning, and soreness. You may notice a white coating in and around the vagina. The pain tends to feel like irritation and rawness, especially during urination or sex.
Bacterial vaginosis (BV) is a different situation. BV produces grayish, foamy discharge with a noticeable fishy smell. The pain is usually milder, more of a burning or irritation rather than the intense itch of a yeast infection. BV happens when the natural balance of bacteria in the vagina shifts, and it’s not always sexually transmitted. Both conditions are treatable, but using an over-the-counter yeast treatment when you actually have BV won’t help, so getting the right diagnosis matters.
Sexually Transmitted Infections
Several STIs can cause vaginal or vulvar pain. Trichomoniasis is one of the most common, with over two million infections estimated in the U.S. in 2018 alone. About 70% of people with trich have no symptoms at all, which is part of why it spreads so easily. When symptoms do show up, they include itching, burning, redness, soreness, discomfort while peeing, and a thin discharge that may be clear, white, yellowish, or greenish with a fishy smell. Sex often becomes uncomfortable or unpleasant. Symptoms can appear anywhere from 5 to 28 days after exposure, or much later, and they sometimes come and go.
Chlamydia and gonorrhea can also cause pain, unusual discharge, and burning during urination. These infections sometimes produce no symptoms at all in the early stages, which is why routine screening is important if you’re sexually active. Left untreated, they can spread to the uterus and fallopian tubes, causing pelvic inflammatory disease (PID), a more serious infection that brings fever, severe lower abdominal pain, and can affect fertility.
Friction and Minor Tears
Pain after sex is extremely common and often comes down to something mechanical. Insufficient lubrication, vigorous friction, or a position that doesn’t quite work can cause tiny tears or abrasions in the vaginal wall or at the vaginal opening. This type of pain usually feels sharp or stinging and is most noticeable afterward or the next day. Most minor vaginal tears heal on their own within a day or two. If the soreness, bleeding, or discomfort hasn’t improved after a week, that’s worth a call to your healthcare provider.
Pelvic Floor Muscle Tension
Your pelvic floor is a group of muscles that stretches across the bottom of your pelvis, supporting your bladder, uterus, and rectum. When these muscles go into a state of constant contraction or spasm (called a hypertonic pelvic floor), the result is pain that can be confusing because it doesn’t always feel like a “muscle” problem. You might feel general pressure or aching in your pelvic area, low back, or hips. The pain can also be sharp and specific, flaring during sex, bowel movements, or even passing gas.
This condition is more common than most people realize. Stress, anxiety, past injuries, chronic holding patterns (like clenching when you’re tense), and even prolonged sitting can contribute. Unlike weak pelvic floor muscles that benefit from kegel exercises, a hypertonic pelvic floor actually needs the opposite: learning to relax and release those muscles, often with the help of a pelvic floor physical therapist.
Low Estrogen and Vaginal Dryness
Estrogen keeps vaginal tissue thick, elastic, and naturally lubricated. When estrogen drops, whether from menopause, breastfeeding, certain medications, or surgical removal of the ovaries, the vaginal lining becomes thinner, drier, and more fragile. The vaginal canal can actually shorten and tighten over time. This makes sex painful and can cause light bleeding afterward, but the discomfort isn’t limited to sex. Everyday activities, sitting, or even wearing fitted clothing can feel irritating.
This condition is most common during and after menopause, but it can affect younger people too. Hormonal birth control, cancer treatments, and the postpartum period can all lower estrogen enough to cause these changes. Moisturizers designed for vaginal tissue, lubricants during sex, and in some cases prescription estrogen therapy can help restore comfort.
Vulvodynia: Pain Without a Clear Cause
If you’ve been dealing with vulvar pain for weeks or months and tests keep coming back normal, vulvodynia may be the answer. This is chronic pain of the vulva that persists without an identifiable infection, skin condition, or injury to explain it. The pain can be constant or triggered by touch, sitting, or inserting a tampon. It often feels like burning, stinging, rawness, or throbbing.
Diagnosing vulvodynia involves ruling out other causes. A provider will typically do a pelvic exam, test for infections, check your pelvic floor muscles for tension, and use a cotton swab to gently map specific areas of pain on the vulva. A biopsy or blood work to check hormone levels may follow if the skin looks unusual. Vulvodynia is real, it’s not “in your head,” and it’s treatable with a combination of approaches including pelvic floor therapy, topical treatments, and nerve-targeted strategies.
Skin Conditions on the Vulva
The vulva is skin, and it can develop the same kinds of conditions that affect skin elsewhere on your body. Lichen sclerosus is one of the more common ones. It causes smooth, discolored patches of skin that may look white or lighter than your normal skin tone. The affected skin becomes thin, wrinkled, and fragile, bruising and tearing easily. Itching is often the dominant symptom, but soreness, burning, blistering, and painful sex are all part of the picture.
Lichen sclerosus isn’t contagious and isn’t caused by poor hygiene. It’s thought to be related to an overactive immune response. It does need treatment because untreated cases can cause scarring that changes the anatomy of the vulva over time.
Signs That Need Prompt Attention
Most causes of vaginal or vulvar pain are not emergencies, but certain combinations of symptoms point to something that needs quick treatment. Fever above 101°F combined with lower abdominal pain, severe nausea or vomiting, or pain so intense it’s hard to function could signal pelvic inflammatory disease or another serious infection. Unusual bleeding, especially if you’re pregnant, also warrants immediate care. Pain that started after a new sexual partner and comes with discharge or burning during urination is worth getting tested sooner rather than later, since untreated STIs can cause lasting damage.
