Vaginal pain has many possible causes, ranging from common infections that clear up quickly to chronic conditions that need ongoing management. The sensation you’re feeling, whether it’s burning, aching, stinging, or a sharp pain during sex, is one of the most important clues to figuring out what’s going on. Most causes are treatable, and narrowing down the type of pain and where exactly you feel it can help you and your healthcare provider get to an answer faster.
Where the Pain Is Matters
What most people call “vaginal pain” can actually originate from a few different areas. The vulva is the external tissue you can see, including the labia and the area around the vaginal opening (called the vestibule). The vaginal canal is the internal passage. Pain in each area points toward different causes.
External burning, stinging, or soreness that flares when you sit, wear tight clothing, or wipe often points to vulvar conditions or skin irritation. Pain that you feel deeper inside, especially during sex or with tampon use, is more likely related to infections, hormonal changes, or pelvic floor issues. Some conditions cause both. Paying attention to when the pain happens, what triggers it, and exactly where it’s centered will help you describe it clearly if you seek care.
Yeast Infections and Bacterial Vaginosis
These two infections are among the most common reasons for vaginal discomfort, and they feel quite different from each other. A yeast infection typically causes itching, burning, and pain in the vulva or vagina, often with a thick, white, odorless discharge. You may notice a white coating in and around the vagina. Some people also feel a stinging sensation when they urinate, especially if the vulvar skin is already irritated.
Bacterial vaginosis (BV) is caused by an imbalance in the bacteria that normally live in the vagina. It often produces a grayish, foamy discharge with a fishy smell, though it’s also common for BV to cause no noticeable symptoms at all. Both infections can cause pain or discomfort during sex. Yeast infections tend to be itchier, while BV is more likely to announce itself through odor and discharge changes. Over-the-counter treatments exist for yeast infections, but BV typically requires a prescription.
Sexually Transmitted Infections
Several STIs cause vaginal pain as a primary symptom, and some of them can be easy to mistake for a yeast infection if you’re not tested.
- Chlamydia can cause vaginal pain during sex, lower abdominal pain, and unusual discharge. It frequently produces no symptoms at all in the early stages, which is why routine screening matters.
- Gonorrhea causes pelvic or stomach pain and may produce thick, cloudy, or bloody discharge.
- Trichomoniasis causes vaginal itching, burning, soreness, and pain during sex. Discharge is often clear, white, greenish, or yellowish, sometimes with a strong fishy odor.
- Genital herpes produces pain or itching around the genital area, buttocks, and inner thighs. You may notice small red bumps, blisters, or open sores. Some people also feel pressure in the lower abdomen.
If your pain came on suddenly, appeared after a new sexual partner, or is accompanied by unusual discharge, getting tested is the most direct path to relief. Many of these infections are highly treatable once identified.
Hormonal Changes and Vaginal Dryness
When estrogen levels drop, the tissues lining the vagina become thinner, drier, less elastic, and more fragile. This is called vaginal atrophy, or genitourinary syndrome of menopause. It causes dryness, burning, itching, soreness, and pain during sex due to reduced lubrication. Urination can also sting or burn.
Menopause is the most common trigger, but estrogen can also dip during breastfeeding, after certain cancer treatments, or while taking some medications. The pain tends to develop gradually rather than appearing overnight, and it often gets worse over time without treatment. Vaginal moisturizers and estrogen-based treatments prescribed by a provider can make a significant difference.
Chronic Vulvar and Pelvic Floor Pain
Some people experience vulvar or vaginal pain that lasts for months without a clear infection or injury to explain it. Vulvodynia is defined as vulvar pain persisting for at least three months without an identifiable cause. Population-based surveys in the U.S. estimate that 10 to 28 percent of women will experience vulvodynia at some point in their lives, making it far more common than most people realize.
The pain can be generalized, affecting the entire vulva, or localized to the vestibule (the tissue surrounding the vaginal opening). Localized vulvodynia is more common than the generalized type. It often feels like burning, stinging, or rawness and can be triggered by touch, sitting for long periods, or sex.
A related condition, vaginismus, involves involuntary spasms of the pelvic floor muscles that make penetration painful or impossible. It can develop on its own or as a secondary response to vulvodynia or other pain conditions. The two overlap frequently: many people with chronic vulvar pain develop some degree of pelvic floor tightening over time. Treatment typically involves pelvic floor physical therapy, sometimes combined with other approaches depending on the individual.
Pain After Childbirth
If you recently gave birth vaginally, soreness in and around the vagina is expected. The entire perineal area (the tissue between the vaginal opening and the anus) may be sore, swollen, and tender for several weeks. This is a normal part of recovery.
The key thing to track is direction: you should generally feel better over time, not worse. New pains or an increase in pain after you’ve already started improving are signals that something else may be going on, such as an infection at a tear or episiotomy site. Persistent pain that isn’t gradually easing after a few weeks is worth bringing up with your provider.
Signs That Need Urgent Attention
Most vaginal pain resolves with straightforward treatment, but certain combinations of symptoms require immediate care. Sharp, sudden pelvic pain accompanied by excessive vaginal bleeding, fever, nausea or vomiting, or signs of shock like fainting should be treated as an emergency. These can indicate pelvic inflammatory disease (a complication of untreated STIs that can damage reproductive organs), an ectopic pregnancy, or a ruptured ovarian cyst.
Fever combined with vaginal pain and unusual discharge is a particularly important combination. It suggests the infection may have spread beyond the vagina into the uterus or fallopian tubes, which needs prompt treatment to prevent lasting damage.
