Vaginal pain has many possible causes, and what you should do depends on the type of pain, where exactly you feel it, and whether it came on suddenly or has been building over time. The good news is that most causes are treatable, and many respond to simple changes you can make at home while you figure out the underlying issue.
Start With Immediate Relief
If you’re hurting right now, a sitz bath is one of the simplest ways to calm irritated tissue. Fill your bathtub or a plastic basin with 3 to 4 inches of warm water, around 104°F, and soak for 15 to 20 minutes. Use plain warm water only. Epsom salts, oils, and other additives can actually cause more inflammation. You can repeat this three to four times a day if it helps.
While you’re sorting out the cause, stop using anything scented near your vulva and vagina: perfumed soaps, bubble baths, scented pads, fragranced wipes, and douches. These products disrupt the vaginal environment and can worsen irritation. Wear loose, breathable cotton underwear and avoid tight clothing that traps heat and moisture against the skin.
Common Causes of Vaginal Pain
Vaginal pain isn’t a single condition. It’s a symptom with a wide range of possible explanations, some simple and some more complex. Here are the most likely ones.
Infections
Yeast infections cause swelling, itching, and pain, especially during sex or urination. They’re one of the most common reasons for sudden vaginal discomfort. Bacterial vaginosis, or BV, happens when the normal balance of bacteria in the vagina is disrupted. It often causes irritation, itching, and a fishy-smelling discharge. Both are treatable, but they require different medications, so getting the right diagnosis matters. Over-the-counter antifungal treatments work for yeast infections, but BV needs a prescription antibiotic.
Sexually transmitted infections can also cause vaginal pain. Chlamydia symptoms typically appear 5 to 14 days after exposure and can include pain during sex. Gonorrhea symptoms tend to show up within 10 days and often involve burning with urination and pelvic pain. Trichomoniasis causes itching, burning, soreness, and pain during sex, with symptoms appearing anywhere from 5 to 28 days after exposure. Genital herpes produces raw, painful sores that last 3 to 14 days, and the first outbreak tends to be the most painful.
Vaginal Dryness
A lack of lubrication along the vaginal lining can make sitting, exercising, urinating, and having sex genuinely painful. Dryness is especially common during and after menopause, when falling estrogen levels cause the vaginal lining to become thinner, less stretchy, and more fragile. The vaginal canal can actually narrow and shorten, and the tissue receives less blood flow. But dryness also affects younger people during breastfeeding, while taking certain medications, and sometimes without an obvious trigger.
For mild dryness, a water-based or silicone-based lubricant during sex can make a significant difference. If dryness is persistent and related to hormonal changes, topical estrogen applied directly to the vagina (as a cream, a small tablet, or a slow-release ring) treats the root cause without significantly raising estrogen levels elsewhere in the body.
Pelvic Floor Muscle Tension
Your pelvic floor is a group of muscles that supports your bladder, uterus, and rectum. When these muscles go into spasm or stay in a state of constant contraction, the result is pain that can be persistent and hard to pin down. It often shows up as deep aching, pain during sex, difficulty with urination or bowel movements, or a general sense of pressure. Pelvic floor tension frequently develops as a reflexive response to other types of pain in the area, creating a frustrating cycle.
Pelvic floor physical therapy is highly effective for this. A specialized physical therapist works with you to retrain these muscles to relax and contract normally. Most people experience partial or complete relief with treatment, though it takes time and consistency.
Vulvodynia and Vaginismus
Vulvodynia is chronic vulvar pain lasting at least three months with no identifiable cause. It can feel like burning, stinging, throbbing, or rawness, and the pain may be triggered by touch (sex, tampon insertion, even sitting for long periods) or occur spontaneously. Diagnosis often involves a simple test where a provider touches different areas around the vaginal opening with a cotton swab to map where the pain is located.
Vaginismus is different. It involves involuntary tightening of the muscles around the vagina, which can make penetration painful, difficult, or impossible. This includes sex, tampon use, and even pelvic exams. It often comes with significant anxiety about penetration. Both conditions are real, recognized medical problems with effective treatments ranging from physical therapy to targeted medications.
Structural and Reproductive Causes
Endometriosis, where tissue similar to the uterine lining grows outside the uterus, is a common source of pelvic and vaginal pain. Uterine fibroids (noncancerous growths in the uterus) can cause heavy periods, back pain, and pain during sex. Bartholin’s cysts develop when the glands near the vaginal opening become blocked, forming tender lumps that can become infected and fill with pus. These conditions all require a healthcare provider’s evaluation to diagnose and manage.
Pain During or After Sex
Pain with intercourse is common enough to have its own medical name: dyspareunia. Insufficient lubrication is one of the most frequent causes, and it’s often the easiest to address. Use a water-based or silicone-based lubricant, and give yourself more time for arousal before penetration.
If lubrication isn’t the issue, try different positions. Pain that’s worse in certain positions may point to a specific cause, like endometriosis or pelvic floor tension. Taking an over-the-counter pain reliever before sex and applying an ice pack to the vulva afterward can help manage throbbing or aching. Relaxation matters too: stress and anxiety tighten pelvic muscles, which amplifies pain.
Pain during sex that’s new, worsening, or accompanied by unusual discharge or bleeding is worth getting checked out. It could signal an infection, a hormonal change, or a condition like vulvodynia that responds well to targeted treatment once identified.
Physical Injury and Irritation
Sometimes the cause is straightforward. A nick from shaving, irritation from waxing, or a reaction to a new laundry detergent can all cause vulvar and vaginal discomfort. Childbirth can result in vaginal tearing that takes weeks to fully heal. Resuming sex too soon after childbirth or surgery is another common trigger.
For minor cuts or irritation, keeping the area clean with plain water, wearing loose clothing, and giving it time is usually enough. Avoid applying creams, ointments, or antiseptics unless directed by a provider, as these can further irritate delicate tissue.
What About Vaginal Probiotics?
Vaginal probiotics, whether taken orally or inserted directly, are marketed as a way to support healthy vaginal bacteria. There is currently no evidence that they improve the bacterial balance in the vagina. Probiotics are living organisms that must survive manufacturing and the journey to the vaginal tissue, and researchers haven’t yet developed products that reliably do this. Save your money unless a healthcare provider specifically recommends one.
Signs You Need Medical Attention
Some symptoms call for a provider visit sooner rather than later. Fever, chills, or pelvic pain alongside vaginal discomfort could indicate a spreading infection. Unusual discharge with a strong odor, especially if it’s new, may point to BV or an STI that needs treatment. If you’ve recently had a new sexual partner or multiple partners, getting tested is important because several STIs cause vaginal pain but can be mistaken for a yeast infection.
You should also see a provider if you’ve tried over-the-counter antifungal treatment and your symptoms haven’t improved, if you’ve never had a vaginal infection before and aren’t sure what you’re dealing with, or if the pain has lasted more than a few days without an obvious cause. Vaginal pain that persists for weeks or months, even at a low level, is worth investigating rather than pushing through.
