Vaginal pain has many possible causes, ranging from a simple irritation that clears up on its own to infections or chronic conditions that need treatment. The type of pain you’re feeling, where exactly it is, and what makes it worse all point toward different explanations. Here’s a breakdown of the most common reasons and what to look for with each one.
Infections Are the Most Common Cause
If your pain came on recently and is paired with unusual discharge, an infection is the most likely explanation. The three most common culprits are yeast infections, bacterial vaginosis, and sexually transmitted infections, and each feels a little different.
A yeast infection typically causes itching and redness of the vagina and vulva. The discharge is thick, white, and often looks like cottage cheese. It usually doesn’t smell. The dominant sensation is intense itching, though soreness and burning during urination are common too.
Bacterial vaginosis (BV) feels different. The discharge is thin and grayish-white, and there’s often a strong fishy smell, especially after sex. BV can cause irritation, but it’s generally less intensely itchy than a yeast infection. Many people with BV don’t have pain at all, just the noticeable odor and discharge change.
Sexually transmitted infections can also cause vaginal pain. Chlamydia and gonorrhea both produce burning during urination, pain during sex, and lower abdominal or pelvic pain. Trichomoniasis causes vaginal itching, burning, and soreness along with a frothy, sometimes greenish discharge. Genital herpes produces pain or itching around the genital area, buttocks, and inner thighs, and during a first outbreak you may also feel flu-like symptoms such as headache and muscle aches. Herpes sores can make urination painful, and the tenderness lasts until the infection clears.
Products That Irritate Sensitive Tissue
The skin of the vulva and the tissue inside the vagina are more sensitive than other parts of your body, and everyday products can trigger inflammation and pain. This is called contact dermatitis, and it’s more common than most people realize.
Known triggers include soap, bubble bath, shampoo, perfume, douches, laundry detergent, dryer sheets, talcum powder, and even toilet paper. Pads, panty liners, tampons, spermicides, and underwear made from synthetic materials like nylon can also cause reactions. Tea tree oil, certain dyes, and nickel (from body jewelry) are on the list too.
If your pain started shortly after switching to a new product, that’s a strong clue. The fix is straightforward: stop using the suspected product and switch to fragrance-free, dye-free alternatives. If the irritation doesn’t improve within a week, it’s worth getting checked out.
Hormonal Changes and Vaginal Dryness
If you’re in your 40s or older and noticing that sex has become painful or that you feel dry and raw, lower estrogen levels are a likely cause. As estrogen drops during the years leading up to menopause and beyond, vaginal tissue becomes thinner, drier, less elastic, and more fragile. This can make intercourse painful and leave the area feeling sore even without any activity.
Some people notice symptoms during perimenopause, while others don’t have problems until several years into menopause. Breastfeeding and certain medications can also lower estrogen enough to cause similar dryness and discomfort at younger ages. Treatments that restore moisture and elasticity are available, so this isn’t something you need to just live with.
Pelvic Floor Muscle Problems
Your pelvic floor is a group of muscles that supports your bladder, uterus, and rectum. Normally these muscles tighten and relax as needed. But sometimes they stay clenched, and that constant tension creates ongoing pain in the pelvic region, genitals, or rectum. It can also make sex painful.
This kind of pain often feels deep, achy, or pressure-like, and it may not be tied to any visible irritation or discharge. Stress, past injuries, or even habitually holding tension in the body can contribute. Physical therapy focused on pelvic floor relaxation is one of the primary treatments.
Chronic Pain Without a Clear Cause
About 4% of women experience vulvar pain lasting six months or longer at any given time, and roughly 1 in 10 will deal with it at some point in their lives. Two conditions fall into this category.
Vulvodynia is chronic pain, burning, itching, or discomfort of the vulva (the external area including the labia, clitoris, and vaginal opening) with no identifiable cause. There’s no infection, no visible rash, no clear trigger. The pain can be constant or come and go, and it can range from mildly annoying to severe enough to interfere with sitting, exercise, or wearing fitted clothing.
Vaginismus is different. It involves involuntary tightening or spasming of the muscles around the vagina. This can make penetration during sex difficult or impossible and often involves significant anxiety about the anticipated pain. Some people with vaginismus also struggle with tampon use or pelvic exams.
Both conditions are treatable, but they take time. Treatment plans often need at least three months before meaningful improvement shows up, so patience matters.
How to Tell What’s Going On
Paying attention to a few details can help you (and a provider, if needed) narrow things down quickly:
- Location: Pain on the outer skin (vulva) points toward irritation, dermatitis, or vulvodynia. Pain inside the vagina or deeper in the pelvis suggests an infection, pelvic floor issue, or hormonal changes.
- Timing: Pain only during sex could mean vaginismus, dryness, or an infection like chlamydia. Pain that’s constant or worsens with sitting may point to vulvodynia or pelvic floor tension.
- Discharge: Cottage cheese texture suggests yeast. Thin, gray, and fishy suggests BV. Green or frothy suggests trichomoniasis. No unusual discharge makes infection less likely.
- Recent changes: New soap, detergent, partner, or medication can all be relevant.
Signs You Shouldn’t Wait
Some situations call for a prompt visit rather than watching and waiting. You should be seen if you have a fever along with pelvic pain, which could signal an infection that has spread beyond the vagina. New vaginal discharge in girls under 10 or in postmenopausal women also warrants evaluation. If you’re pregnant and notice a change in your discharge, get it checked. A new sexual partner (or a suspicion that your partner has a new partner) is another reason, since a change in discharge can signal a sexually transmitted infection.
If you’ve tried treating what you thought was a yeast infection and it hasn’t cleared up within a week, or if there’s a noticeable odor, it’s likely something other than yeast and you’ll need testing to sort it out. A provider will typically do a pelvic exam along with swabs that can test for yeast, bacterial vaginosis, and STIs like gonorrhea, chlamydia, and trichomoniasis, often from a single sample.
