Vaginal pain has many possible causes, ranging from a simple irritant like a new soap to infections, hormonal changes, or chronic conditions. The sensation might be sharp, burning, aching, or a general soreness, and where and when you feel it offers important clues about what’s going on. About 16% of women experience chronic vulvar pain at some point, so this is far from rare, even though it’s not always easy to talk about.
Infections That Cause Vaginal Pain
Infections are one of the most common reasons for vaginal discomfort, and the type of pain helps distinguish which one you might be dealing with.
Yeast infections cause thick, cottage cheese-like discharge along with itching, burning, and pain, especially after sex. Bacterial vaginosis, by contrast, produces a thin grayish discharge that can be heavy in volume but typically causes irritation rather than actual pain. Both involve a disruption in the normal balance of bacteria or yeast in the vagina, but they feel quite different and require different treatments.
Sexually transmitted infections are another major category. Chlamydia can cause pain during sex. Gonorrhea often produces pelvic or stomach-area pain. Trichomoniasis brings itching, burning, soreness, and pain during sex. Genital herpes causes pain or itching around the genitals, buttocks, and inner thighs, sometimes with visible sores. Many of these infections can be present without obvious symptoms for weeks or months, so new or unexplained vaginal pain is worth getting tested for, particularly if you have a new sexual partner.
Everyday Irritants You Might Not Suspect
Sometimes the culprit is something in your daily routine. Vulvar dermatitis, a skin reaction on the external genital area, can cause burning, stinging, and soreness that feels like it’s coming from inside the vagina. Common triggers include soap, bubble bath, shampoo, laundry detergent, perfume, douches, pads, panty liners, tampons, toilet paper, synthetic underwear (like nylon), spermicides, and even dryer sheets. Tea tree oil, often marketed as a natural remedy, is also a known irritant.
If your pain started around the same time you switched a product, that’s a strong clue. Switching to fragrance-free, dye-free products and wearing cotton underwear can resolve irritant-related pain within days to a couple of weeks.
Pain During Sex: Superficial vs. Deep
If your pain happens primarily during intercourse, the location of the pain matters. Superficial pain, felt right at the vaginal entrance during initial penetration, points toward dryness, hormonal changes, chronic irritation, infection, or injury to the tissue. Deep pain, felt further inside during penetration, suggests conditions affecting the bladder, bowel, pelvic floor muscles, or the uterine lining. Endometriosis is one well-known cause of deep pain during sex, and it often feels worse in certain positions.
Pain during sex isn’t something you need to push through. It’s a signal that something specific is happening, and in most cases it can be treated once the cause is identified.
Hormonal Changes and Vaginal Dryness
Estrogen plays a direct role in keeping vaginal tissue thick, elastic, and lubricated. It increases blood flow to the vaginal walls, which supports natural moisture. When estrogen drops, whether during menopause, breastfeeding, or from certain medications, the vaginal lining thins out, loses elasticity, and produces less lubrication. The tissue becomes more fragile and more easily irritated, which can cause a persistent burning, stinging, or raw feeling even without any sexual activity.
This condition, sometimes called vaginal atrophy, affects a large percentage of postmenopausal women but can also occur in younger women with low estrogen levels. The discomfort tends to be ongoing rather than occasional, and it often gets worse over time without treatment. Topical estrogen therapy and non-hormonal moisturizers are the most common approaches.
Chronic Pain Conditions: Vulvodynia and Vaginismus
Vulvodynia is chronic pain, burning, itching, or discomfort of the vulva (the external genital area, including the labia, clitoris, and vaginal opening) with no identifiable cause like an infection or skin condition. The pain usually occurs with contact, such as during sex or when inserting a tampon, but it can also show up spontaneously. Sitting for long periods or exercising can make it worse.
Diagnosis often involves a cotton swab test, where a provider gently touches different areas around the vaginal opening and asks whether each spot feels like pressure or pain. Many women with vulvodynia describe finally having their pain pinpointed for the first time during this test. Treatment varies and can include topical medications, physical therapy, and nerve-targeted approaches.
Vaginismus is different. It involves involuntary tightening of the muscles around the vagina, which can make penetration painful, difficult, or impossible. It often comes with significant anxiety or fear around anything involving vaginal penetration, including pelvic exams and tampon use. The muscle contraction isn’t something you’re choosing to do, and it responds well to pelvic floor physical therapy, which gradually retrains the muscles to relax.
How Vaginal Pain Gets Diagnosed
A provider will typically start with a pelvic exam, checking externally for signs of infection, skin changes, or visible irritation. They may take a sample of vaginal cells to test for yeast or bacterial infections. A gloved finger inserted into the vagina can check for pelvic floor muscle tenderness, which helps identify conditions like vaginismus or pelvic floor dysfunction.
If the skin of the vulva looks unusual, a small biopsy (tissue sample) may be taken for lab analysis. Blood tests can check hormone levels, including estrogen, progesterone, and testosterone, which helps identify hormonal causes. For deeper pain, imaging like an ultrasound may be used to look at the uterus, ovaries, and surrounding structures.
The key information to bring to your appointment: where exactly the pain is, when it started, whether it’s constant or triggered by specific activities, what it feels like (burning, aching, sharp, raw), and whether you’ve noticed any discharge, bleeding, or changes in your cycle.
Signs That Need Prompt Attention
Most vaginal pain isn’t an emergency, but certain combinations of symptoms warrant a same-day or urgent visit. Vaginal pain alongside fever, chills, or pelvic pain can signal a more serious infection like pelvic inflammatory disease, which needs treatment quickly to prevent complications. Unexplained vaginal bleeding or spotting paired with pain also warrants a prompt evaluation. Pain that’s severe, sudden, and unlike anything you’ve felt before should be assessed right away rather than monitored at home.
