Some itching, redness, or mild irritation of the vulva is common and often clears up on its own once a trigger — like a new soap or tight clothing — is removed. But symptoms that are severe, that don’t improve, or that keep coming back are a sign it’s time to see a clinician rather than wait it out. This page explains typical vulvar anatomy, common causes of irritation, and the symptoms that call for prompt medical attention.

Warning Signs to Act On Promptly
Contact a healthcare provider without delay if you notice any of the following:
- A new lump, sore, ulcer, or area of skin color change that doesn’t go away
- Persistent itching, burning, or pain that lasts for weeks or keeps coming back
- Bleeding or discharge that is not related to your period
- A mole or freckle on the vulva that changes in size, shape, or color
- Significant swelling, especially with fever, chills, or spreading redness
These symptoms don’t automatically mean something serious is wrong, but a clinician needs to examine the area to find the cause. Some, like a mole that’s changing or a sore that won’t heal, are the kind of change worth having a professional look at rather than waiting to see if it resolves.
Normal Vulvar Anatomy and Everyday Variation
The vulva is the external part of the female genitals — it includes the labia majora and labia minora (outer and inner folds of skin), the clitoris, and the opening of the vagina and urethra. Vulvas naturally vary a great deal from person to person in size, shape, color, and symmetry, and there is no single “normal” appearance. Some day-to-day changes are typical too, including mild swelling or color changes tied to your menstrual cycle, arousal, or temperature, and some odor and discharge that changes across the cycle.
Small bumps around hair follicles, visible oil glands, and slight asymmetry between the left and right labia are common and are not, by themselves, signs of a problem.
Common Causes of Vulvar Irritation
Vulvar irritation has many possible causes. A clinician can help sort out which one applies to you. Common categories include:
- Contact irritation or allergy. Soaps, laundry detergent, fragranced pads or tampons, wipes, and certain fabrics can irritate sensitive vulvar skin.
- Friction. Shaving, waxing, tight clothing, or prolonged sitting can cause small, red, sometimes painful bumps where hair follicles become irritated or infected. This often goes away on its own.
- Infections. Yeast infections and sexually transmitted infections, such as genital herpes, can cause itching, discharge, or sores. If you think you may have been exposed to an STI, our STI & Sexual Health guide covers routine screening.
- Skin conditions. Chronic conditions such as lichen simplex chronicus, lichen sclerosus, and lichen planus can cause ongoing itching, pain, or changes in skin texture and color, and generally need a clinician’s diagnosis and follow-up.
- Other medical conditions. Some digestive conditions, such as Crohn disease, can cause inflammation, swelling, sores, or bumps on the vulva as part of the broader condition.
Because several of these causes can look similar, a home guess isn’t reliable — a clinician can examine the skin, ask about your symptoms and routine, and, when needed, take a sample of discharge or a small tissue sample (biopsy) to confirm the cause.
Self-Care Steps That May Help With Mild Irritation
For everyday irritation without warning signs, some general self-care habits may help prevent or ease symptoms:
- Rinse the vulva with warm water and gently pat, rather than rub, it dry.
- Wear cotton underwear, and avoid tight-fitting pants.
- Skip pantyhose unless it has a cotton crotch.
- Avoid pads or tampons with added deodorant or a plastic coating.
- Avoid scented sprays, “feminine hygiene” products, and douching, since these can disrupt the vulva and vagina’s normal balance.
These are general habits, not treatment for a diagnosed condition. If symptoms don’t improve with basic care, or if they’re severe, see a provider rather than continuing to self-treat.
Checklist: Should You See a Doctor?
- Is a warning sign present — a lump, sore, changing mole, unusual bleeding, or spreading redness with fever? See a provider promptly.
- Has irritation lasted more than a week or two despite basic self-care? Schedule a visit.
- Have you had similar symptoms before that were diagnosed and treated, and this feels the same? Follow your provider’s earlier guidance, and check back in if it doesn’t resolve the same way.
- Is this new, mild, and tied to an obvious trigger — like a new product or tight clothing? It’s reasonable to remove the trigger and use general self-care for a few days.
- Are you unsure, worried, or is this affecting your daily comfort? That alone is a good enough reason to be seen — you don’t need to wait for a “serious enough” symptom.
Extra-Caution Groups and Evidence Limits
Some situations call for a lower threshold to seek care. Vulvar changes during pregnancy, in children, after menopause, or in anyone with a weakened immune system should be evaluated by a provider rather than managed at home, since causes and appropriate next steps can differ in these groups. A history of abnormal Pap tests, prior cervical or vaginal cancer, smoking, or known HPV infection are also reasons to bring any new vulvar change to a clinician promptly.
This page is a general educational overview. It doesn’t cover every possible cause of vulvar symptoms, diagnostic testing in detail, or treatment options, and it isn’t a substitute for an in-person exam. Vulvar cancer, for example, is rare, but it’s one reason persistent or unusual changes shouldn’t be ignored.
Frequently Asked Questions
Is it normal for the labia to look different on each side?
Yes. Some asymmetry between the left and right labia is common and is not, by itself, a sign of a health problem.
Can shaving or waxing cause vulvar irritation?
Yes. Friction from shaving, waxing, or tight clothing can irritate hair follicles and cause small, red bumps. This often improves on its own, but a provider can help if bumps become painful, infected, or don’t go away.
Do STIs cause vulvar itching or bumps?
Some sexually transmitted infections, including genital herpes, can cause vulvar symptoms such as sores or irritation. Because many STIs don’t cause symptoms at all, routine screening — not just symptom-watching — is part of standard preventive care. See our STI & Sexual Health guide for more.
What should I bring up at a visit for vulvar symptoms?
It helps to note when symptoms started, what makes them better or worse, any new products or hygiene changes, and whether you’ve tried self-care already. Our guide to preparing for a reproductive health visit has more tips on getting ready for an appointment.
