Vaginal and vulvar pain has many possible causes, ranging from a simple irritation that clears up in days to infections that need treatment. The type of pain you’re feeling, whether it’s burning, itching, soreness, or a deeper ache, can point toward what’s going on. Here’s a breakdown of the most common reasons and what to look for with each one.
Infections: The Most Common Cause
If your pain came on relatively suddenly and is accompanied by unusual discharge or odor, an infection is the most likely explanation. The three most common culprits are yeast infections, bacterial vaginosis (BV), and sexually transmitted infections.
Yeast Infections
A yeast infection typically causes intense itching, soreness, and a thick, cottage cheese-like discharge. Pain or burning often gets worse when you pee or during sex. These infections happen when the natural yeast in your vagina overgrows, often triggered by antibiotics, hormonal changes, or a weakened immune system. Over-the-counter antifungal treatments work for most people, but if you’ve tried one and the symptoms haven’t budged, you likely need a different diagnosis.
Bacterial Vaginosis
BV produces a thin, grayish discharge that’s heavier than usual, often with a fishy smell that becomes more noticeable after your period or after sex. The pain tends to feel more like general irritation or burning rather than the sharp itching of a yeast infection. BV develops when the balance of bacteria in your vagina shifts. Semen and menstrual blood both have a higher pH than your vagina, so either one can disrupt that balance and trigger a flare. BV requires prescription antibiotics to clear.
STIs
Trichomoniasis, chlamydia, and gonorrhea can all cause vaginal pain, but they’re tricky because many people have no symptoms at all. About 70% of people with trichomoniasis never notice anything. When trich does cause symptoms, you might see itching, burning, redness, discomfort while peeing, and a clear, white, yellowish, or greenish discharge with a fishy smell. It can also make sex feel unpleasant. Chlamydia and gonorrhea may cause similar symptoms or stay completely silent while still causing damage internally. If you’ve had a new sexual partner or unprotected sex, getting tested is the only way to rule these out.
Products That Irritate Vulvar Skin
Your vulvar skin is significantly more sensitive than the skin on the rest of your body, and a surprising number of everyday products can cause contact dermatitis, a reaction that leads to burning, stinging, redness, and soreness. Common triggers include soap, bubble bath, shampoo and conditioner (from rinsing in the shower), scented laundry detergent, dryer sheets, perfume, deodorant, douches, talcum powder, and even toilet paper with dyes or fragrances. Pads, panty liners, tampons, spermicides, tea tree oil, and underwear made from synthetic materials like nylon are also on the list.
The fix is usually straightforward: stop using the product causing the reaction. If you recently switched detergents, started using a new body wash, or tried a different brand of pads, that’s a good place to start. Washing your vulva with warm water only (no soap) for a few days can help you figure out whether a product is the problem. If the irritation clears up, reintroduce products one at a time to identify the trigger.
Hormonal Changes and Vaginal Dryness
Estrogen plays a major role in keeping vaginal tissue lubricated, elastic, and thick enough to be comfortable. When estrogen drops, the vaginal walls can thin out, dry up, and become inflamed, a condition called vaginal atrophy. Low estrogen also reduces natural vaginal moisture, which can dry and irritate the vulva.
This isn’t just a menopause issue. Estrogen can dip after childbirth, during breastfeeding, while taking certain birth control pills, and in younger people with hormonal imbalances. The pain often shows up as a raw, dry, burning sensation that’s worse during sex. Vaginal moisturizers help with day-to-day comfort, and prescription estrogen creams applied locally can restore tissue thickness without the systemic effects of hormone replacement therapy.
Tight Pelvic Floor Muscles
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 get stuck in a state of constant tension (called a hypertonic pelvic floor), they can cause pain that’s hard to pin down. You might feel general pressure or aching in your pelvic area, pain during or after sex, discomfort during bowel movements, or a sense that something is always “off” down there.
This kind of pain is often mistaken for an infection because it can cause burning and soreness in the same areas. But if swabs and tests keep coming back normal and the pain persists, pelvic floor tension is worth investigating. Stress, anxiety, past injuries, and even habits like clenching during exercise can contribute. Pelvic floor physical therapy, where a specialist helps you learn to relax and coordinate these muscles, is the most effective treatment for most people.
Vulvar Skin Conditions
Certain skin conditions specifically target vulvar tissue. Lichen sclerosus causes smooth, discolored patches of skin that may look white or blotchy. The skin becomes fragile, bruises easily, and can blister or develop open sores. Symptoms include itching, soreness, burning, and pain during sex. It most commonly affects the genital and anal areas, and without treatment, it can cause scarring that changes the shape of the vulvar tissue over time. Lichen sclerosus is managed with prescription steroid creams that keep flares under control.
Chronic Vulvar Pain Without a Clear Cause
If you’ve had persistent vulvar pain for three months or longer and testing hasn’t identified an infection, skin condition, or other treatable cause, you may be dealing with vulvodynia. This is chronic pain localized to the vulva that can feel like burning, stinging, rawness, soreness, or sharp, knife-like sensations. Some people also experience aching, throbbing, and swelling. The pain may be constant or triggered only by touch or pressure, like sitting for long periods, wearing tight pants, or inserting a tampon.
Vulvodynia is a real medical condition, not something you’re imagining, though it can take time to get a diagnosis because doctors need to rule out infections, STIs, herpes, inflammatory skin conditions, and hormonal causes first. Treatment typically involves a combination approach: pelvic floor physical therapy, topical medications to calm nerve sensitivity, and sometimes cognitive behavioral therapy to address the pain-brain connection. Many people see significant improvement, but it often takes patience and working with a provider who specializes in vulvar pain.
What the Type of Pain Can Tell You
Paying attention to exactly what the pain feels like and when it happens can help narrow things down. Itching that’s your primary symptom points toward yeast infections, contact dermatitis, or lichen sclerosus. Burning during urination suggests an infection, either vaginal or urinary. Pain mainly during or after sex could mean dryness, pelvic floor tension, or an internal infection. A deeper, aching pelvic pain, especially with fever or chills, could signal pelvic inflammatory disease, which is a serious complication of untreated STIs that needs prompt medical attention.
If you’ve never had vaginal pain before and aren’t sure what’s causing it, getting examined is worth it even if the symptoms seem mild. Several conditions that start with minor discomfort, like chlamydia or BV, can lead to bigger problems if left untreated. And if you’ve already tried over-the-counter yeast treatments without improvement, the odds are good that yeast isn’t actually the issue.
