Vaginal burning has several common causes, and most of them are treatable once you figure out what’s going on. The sensation can range from a mild sting to an intense, constant fire, and the cause could be anything from a product you recently switched to, an infection, or a hormonal shift. Here’s how to narrow it down and get relief.
The Most Likely Causes
Burning in or around the vagina generally falls into a few categories: irritation from something touching your skin, an infection, hormonal changes, or a chronic pain condition. The clues that help you tell them apart are the type of discharge you have (or don’t), whether the burning started suddenly or built up over time, and whether anything specific seems to trigger it.
Contact Dermatitis: Your Skin Reacting to a Product
This is one of the most overlooked causes, and it’s worth considering first because it’s the easiest to fix. Contact dermatitis happens when the sensitive skin of your vulva reacts to a chemical or material. The list of possible culprits is long: soap, bubble bath, shampoo, laundry detergent, dryer sheets, scented toilet paper, period products with deodorant or plastic coating, synthetic underwear, spermicides, lubricants, and even tea tree oil. Symptoms include extreme itching, rawness, stinging, and burning.
If you recently switched any product that touches that area, or if the burning started without any unusual discharge, this is a strong possibility. The fix is removing the offending product and giving your skin time to heal.
Yeast Infection vs. Bacterial Vaginosis
Both can cause burning, but they look and smell different. A yeast infection typically produces thick, white, odorless discharge, sometimes with a white coating in and around the vagina. Bacterial vaginosis (BV) produces grayish, foamy discharge that smells fishy.
This distinction matters because they’re treated differently. Over-the-counter antifungal treatments (available as 1-day, 3-day, or 7-day courses) work for yeast infections but do nothing for BV. Clinical studies of the 3-day antifungal cream show a cure rate around 59 to 67%, so they work for most people but not everyone. If you try an OTC yeast treatment and the burning doesn’t resolve, that’s a sign it may be something else entirely. BV requires a prescription.
Sexually Transmitted Infections
Trichomoniasis is a common STI that causes itching, burning, redness, and soreness of the genitals, along with discomfort when peeing. Genital herpes can also produce a burning sensation, particularly during an active outbreak when sores or blisters are present. Chlamydia and gonorrhea sometimes cause burning too, though they often show no symptoms at all.
If you’ve had a new or multiple sexual partners recently, STIs should be on your radar. These require testing and prescription treatment.
Hormonal Changes and Menopause
If you’re in your 40s or older, declining estrogen levels could be the cause. Lower estrogen makes vaginal tissue thinner, drier, less elastic, and more fragile. This condition, called genitourinary syndrome of menopause, can cause burning, itching, irritation, pain during sex, and vaginal dryness. Symptoms can start during perimenopause (the years leading up to menopause) or not appear until a few years into menopause. Breastfeeding can cause similar temporary hormonal shifts.
Vulvodynia: When Burning Won’t Go Away
If the burning has lasted longer than three months and no infection, irritant, or hormonal issue explains it, you may be dealing with vulvodynia. This is chronic vulvar pain that isn’t tied to an obvious underlying condition. The pain can feel like burning, stinging, stabbing, itching, rawness, or throbbing, and it ranges from mild to severe. Some people feel it constantly, while others notice it only with touch or pressure (like sitting or sex). Vulvodynia is a diagnosis of exclusion, meaning your provider will rule out other causes first.
What You Can Do Right Now
While you’re figuring out the cause, a few things can ease the burning quickly:
- Cold compress or ice pack. Apply it to the vulvar area (wrapped in a cloth) to numb the sensation.
- Baking soda soak. Add 4 to 5 tablespoons of baking soda to a shallow bath, or 1 to 2 teaspoons to a sitz bath, and soak for 10 minutes. You can do this up to three times a day.
- Petroleum jelly. A thin layer on the outer skin can protect irritated tissue.
- Pour lukewarm water over the vulva while you pee. This dilutes urine so it stings less on raw skin.
At the same time, stop using anything scented or potentially irritating near your vulva. Switch to white, unscented toilet paper (avoid “ultra-soft” or “ultra-strong” varieties and anything with aloe). Skip the hygiene sprays, perfumed soaps, scented period products, and baby wipes. Don’t douche.
Preventing It From Coming Back
The vulvar skin is more reactive than skin on the rest of your body, so long-term prevention is about reducing what touches it and letting it breathe.
Wear white, all-cotton underwear. Not nylon underwear with a cotton crotch panel, but fully cotton. Skip thongs. Avoid tight clothing and synthetic fabrics. At night, loose cotton pajama bottoms or cotton boxers without underwear give the area airflow. If you wear pantyhose, cut out the diamond-shaped crotch area to improve ventilation.
For laundry, use a fragrance-free, dye-free detergent and skip fabric softeners and dryer sheets entirely. If you share a washer, hand-wash your underwear separately. Line dry it when possible.
For hair removal, avoid razors and chemical hair removal products on the vulva. Trimming with scissors is the gentlest option.
Signs You Need Testing
Burning alone can often be managed at home if it’s from an irritant. But certain combinations of symptoms point to something that needs a diagnosis:
- Discharge that’s unusual in color, consistency, or smell
- Pain during urination or sex
- A recent new sexual partner
- Burning that persists after completing an OTC yeast infection treatment
- Sores, blisters, or visible skin changes on the vulva
A provider can distinguish between yeast, BV, STIs, and other conditions with a simple swab or exam, and each one has a different treatment. Getting the right diagnosis is the difference between relief in days and weeks of ongoing discomfort.
