Vaginal burning usually comes from one of a handful of common causes, and the right fix depends on which one is behind it. The most frequent culprits are yeast infections, bacterial vaginosis, contact irritation from products, and hormonal changes related to menopause. Some causes respond to simple changes you can make today, while others need a prescription. Here’s how to figure out what’s going on and what to do about it.
Quick Relief While You Sort Out the Cause
Whatever is causing the burning, a sitz bath can take the edge off. Fill your bathtub or a shallow basin with 3 to 4 inches of warm water (around 104°F) and sit in it for 15 to 20 minutes. Plain warm water is all you need. Epsom salts, oils, and fragrances can actually make irritation worse, so skip them unless specifically told otherwise by a provider. Pat the area dry gently afterward rather than rubbing. You can repeat this up to three or four times a day if it helps.
A cool compress (a clean, damp cloth) held against the vulva can also calm acute stinging. In the short term, applying a thin layer of plain petroleum jelly to the outer skin creates a barrier that protects raw or irritated tissue from further contact with urine, sweat, or clothing. These measures won’t cure the underlying problem, but they can make you significantly more comfortable while you address it.
Product Irritation: The Most Overlooked Cause
Contact dermatitis is one of the most common reasons for vulvar burning, and it’s the easiest to fix. The skin in this area is thinner and more reactive than skin elsewhere on your body, so products that feel fine on your hands or face can cause stinging, rawness, and intense itching down below.
The list of potential irritants is long. Soaps and body washes are frequent offenders, particularly anything containing sodium lauryl sulfate, the foaming agent in most cleansers and shampoos. Beyond soap, documented irritants include douches, feminine wipes, scented pads and panty liners, vaginal deodorants, perfumed toilet paper, laundry detergent, fabric softener, bleach, spermicides, latex condoms, and lubricants with fragrances or warming agents. Even urine or sweat sitting against the skin for extended periods can trigger irritation.
If you suspect a product is the problem, strip your routine back to the basics. Wash the vulva with warm water only, or use an unscented, dye-free cleanser sparingly on the outer skin. Switch to fragrance-free laundry detergent and skip the fabric softener. Wear cotton underwear and avoid tight clothing that traps moisture. Many people notice improvement within a few days of removing the irritant, though skin that’s been inflamed for a while can take a week or two to fully calm down.
Yeast Infections
A yeast infection typically causes burning along with thick, white, cottage cheese-like discharge and intense itching. If you’ve had a yeast infection before and recognize the pattern, over-the-counter antifungal treatments containing miconazole are widely available in several forms: creams, suppositories, and single-day or multi-day regimens ranging from one to seven days. A single-dose oral antifungal pill is also an option but requires a prescription.
These treatments clear the infection in 80% to 90% of people who complete the full course. Most people feel noticeably better within a few days, though more severe infections can take longer. If you’ve never had a yeast infection before, or if symptoms don’t improve after finishing treatment, it’s worth getting tested to confirm the diagnosis. Burning that gets attributed to yeast but is actually something else won’t respond to antifungals, and misdiagnosis is surprisingly common.
Bacterial Vaginosis
Bacterial vaginosis (BV) happens when the balance of bacteria in the vagina shifts, allowing certain species to overgrow. It often produces a thin, grayish discharge with a fishy odor, but burning and irritation are common too. A healthy vagina maintains a pH between 3.8 and 4.5. BV pushes that pH higher, which contributes to the discomfort.
BV requires prescription antibiotics. The standard treatment is a seven-day course of oral antibiotics or a five-to-seven-day course of vaginal antibiotic cream or gel. Unlike yeast infections, there’s no effective over-the-counter option for BV, so you’ll need to see a provider for testing and a prescription.
Sexually Transmitted Infections
Several STIs can cause vaginal burning. Genital herpes often presents as burning or tingling before visible sores appear, and the burning can persist throughout an outbreak. Trichomoniasis, a parasitic infection, frequently causes burning alongside yellow-green discharge and a strong odor. Chlamydia and gonorrhea can also produce burning, though they sometimes cause no symptoms at all.
If burning started after a new sexual partner, came on suddenly without an obvious product change, or is accompanied by unusual discharge, sores, or pelvic pain, STI testing is an important step. All of these infections are treatable, but each requires a specific medication that you can only get through a provider.
Menopause-Related Burning
If you’re in perimenopause or menopause, declining estrogen levels may be the cause. This condition, called genitourinary syndrome of menopause, affects the vaginal and vulvar tissue in ways that produce dryness, burning, itching, pain during sex, and increased susceptibility to urinary tract infections. The tissue becomes thinner, less elastic, and less lubricated, which makes it more vulnerable to irritation from everyday friction.
Vaginal moisturizers are a good first step. These are gel products applied regularly (not just during sex) to supplement the moisture that estrogenized tissue would normally produce on its own. Hyaluronic acid-based moisturizers are one common type. Lubricants are a separate product used specifically during sexual activity to reduce friction. Water-based and silicone-based options are both effective, though oil-based lubricants can degrade latex condoms.
For more persistent symptoms, low-dose vaginal estrogen is the most well-supported treatment. It comes as a cream, tablet, insert, or ring, and it works by restoring estrogen directly to the vaginal tissue rather than throughout the whole body. This is a prescription treatment, and it’s particularly effective for dryness. Many people use moisturizers and vaginal estrogen together for the best results.
How to Identify What’s Causing Your Burning
The pattern of symptoms gives useful clues. Burning that started right after switching soaps, detergents, or pads points to contact irritation. Burning with thick white discharge and itching suggests yeast. A fishy smell with thin discharge suggests BV. Burning that developed gradually over months or years around the time of menopause points to hormonal changes. Burning with sores, blisters, or colored discharge warrants STI testing.
Pay attention to timing, too. Burning only during or after urination could signal a urinary tract infection rather than a vaginal issue. Burning that flares during sex but not at other times may relate to friction, insufficient lubrication, or an underlying skin condition. Burning that’s constant and doesn’t respond to any of the treatments above could indicate vulvodynia, a chronic pain condition of the vulva that requires specialized care.
Preventing Recurrence
Once the burning resolves, a few habits help keep it from coming back. Stick with fragrance-free products for anything that contacts the vulvar area, including soap, detergent, and menstrual products. Avoid douching entirely. It disrupts the vagina’s natural bacterial balance and is linked to higher rates of both BV and yeast infections.
Probiotics get a lot of attention for vaginal health, but the evidence is mixed. The dominant species in a healthy vagina are Lactobacillus crispatus and Lactobacillus iners. Most commercial probiotics contain different species that are more common in the gut. If you want to try a probiotic, the strain with the most supporting data is Lactobacillus rhamnosus GR-1, though results aren’t guaranteed. Wearing breathable fabrics, changing out of wet swimsuits or workout clothes promptly, and wiping front to back are small habits that meaningfully reduce your risk of irritation and infection over time.
