Vaginal pain has dozens of possible causes, ranging from a simple yeast infection to tight pelvic floor muscles to skin irritation from a new soap. About 1 in 7 women of childbearing age experience pelvic pain lasting six months or longer, so this is far from rare. The key to figuring out what’s going on is paying attention to where exactly the pain is, what triggers it, and what other symptoms come with it.
Infections Are the Most Common Cause
If your pain comes with unusual discharge, itching, or a change in smell, an infection is the most likely explanation. The three most common vaginal infections each have a slightly different signature.
A yeast infection produces thick, white, odorless discharge, often with a white coating around the vagina and vulva. The dominant sensation is itching and burning rather than deep pain. Bacterial vaginosis (BV) tends to cause grayish, foamy discharge with a fishy smell, though it sometimes produces no noticeable symptoms at all. Trichomoniasis, a sexually transmitted infection, brings itching, burning, redness, and a thin discharge that can be clear, white, yellowish, or greenish with a fishy odor. All three can make sex uncomfortable and cause stinging when you pee.
These infections are treatable, but they require different medications, so getting the right diagnosis matters. A provider can usually identify the cause with a simple swab.
Irritation From Everyday Products
The vulva and vaginal opening are more sensitive to chemicals than most skin on your body. Contact irritation is an overlooked cause of burning, stinging, and soreness that can feel like an infection but doesn’t involve one. Common triggers include scented soap, bubble bath, laundry detergent, dryer sheets, perfume, douches, and even certain brands of toilet paper. Synthetic underwear fabrics like nylon, menstrual pads, panty liners, and spermicides can also cause reactions.
If your pain started around the same time you switched a product, that’s a strong clue. Switching to fragrance-free detergent, wearing cotton underwear, and washing with plain water for a week or two is often enough to see improvement.
Pelvic Floor Muscles Can Cause Persistent Aching
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 (a condition called hypertonic pelvic floor), the result is pain that can show up in the vagina, lower back, hips, or deep in the pelvis. It often worsens during sex, bowel movements, or prolonged sitting.
This kind of pain tends to be harder to pin down. It may feel like a dull ache or pressure rather than a sharp sting, and there’s no discharge or visible irritation to explain it. Stress, anxiety, past injuries, and habits like chronically clenching your core can all contribute. Pelvic floor physical therapy, where a specialist helps you learn to relax and retrain those muscles, is the standard treatment.
Chronic Vulvar Pain Without a Clear Cause
Some people experience burning, stinging, or rawness at the vaginal opening or across the vulva that lasts for months with no visible infection or injury. This is called vulvodynia, and when the pain is concentrated specifically at the vaginal entrance, it’s known as vestibulodynia.
Vestibulodynia can be provoked, meaning it flares when something touches or puts pressure on the area (inserting a tampon, having sex, even sitting for too long), or it can be unprovoked and present almost constantly. Some people develop it after years of pain-free penetration, which can be confusing and frustrating. There’s no single test that confirms it. Diagnosis typically involves a provider gently pressing a cotton swab against different spots around the vulvar area while you rate the pain, mainly to rule out other conditions.
Treatment usually combines approaches: topical medications to calm nerve sensitivity, pelvic floor physical therapy, and sometimes cognitive behavioral therapy to address the way the nervous system processes pain signals.
Hormonal Changes 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 thins out and becomes drier, less flexible, and more fragile. This is sometimes called genitourinary syndrome of menopause, but it can happen at any age when estrogen is low.
Symptoms include dryness, burning, itching, pain during sex, light bleeding after sex, and a feeling that the vaginal canal has become tighter or shorter. Frequent urinary tract infections and bladder urgency often come along with it. Over-the-counter vaginal moisturizers can help with mild dryness, and prescription estrogen applied locally to the vagina is effective for more significant symptoms.
Pain During Sex Has Two Distinct Patterns
If your pain is primarily triggered by intercourse, it helps to notice exactly when and where it happens. Entry pain, felt right at the vaginal opening during initial penetration, points toward dryness, infection, skin irritation, vestibulodynia, or hormonal changes. Deep pain, felt further inside during thrusting, suggests something different: conditions affecting the bladder or bowel, endometriosis, pelvic floor dysfunction, or pelvic congestion syndrome.
This distinction gives your provider a useful starting point. Being specific about the location and timing of your pain, even if the conversation feels awkward, speeds up the diagnostic process considerably.
What a Diagnostic Workup Looks Like
If you see a provider for vaginal pain, expect a conversation about your symptoms followed by a pelvic exam. During the exam, your provider visually checks the vulva for redness, swelling, or skin changes, then uses a speculum (a smooth, duck-bill-shaped instrument) to gently hold the vaginal walls apart so they can see the vagina and cervix. They may collect a swab to test for infections or a Pap smear to screen for cervical cell changes.
A bimanual exam, where the provider places two gloved fingers inside the vagina while pressing on your lower abdomen with the other hand, lets them feel for tenderness or abnormalities in the uterus and ovaries. The whole process takes a few minutes. If the cause isn’t obvious from these steps, you may be referred for imaging or to a specialist.
Signs That Need Urgent Attention
Most causes of vaginal pain are not emergencies, but a few combinations of symptoms warrant prompt medical care. Severe pelvic pain paired with fever above 101°F (38.3°C), nausea, or vomiting can signal pelvic inflammatory disease, an infection that spreads from the vagina or cervix into the uterus and fallopian tubes. Left untreated, PID can cause lasting damage to the reproductive organs. If you’re experiencing that combination, seek care the same day rather than waiting for a routine appointment.
