A bump on or around your vulva is extremely common and usually not dangerous. Most turn out to be clogged pores, ingrown hairs, or small cysts that resolve on their own. That said, some bumps signal an infection or other condition worth getting checked, so knowing what to look for matters.
The Most Common Causes
The vast majority of bumps in this area fall into a few categories. Figuring out which one applies to you starts with paying attention to where the bump is, what it looks like, and whether it hurts.
Ingrown Hairs and Folliculitis
If you shave, wax, or remove hair in the bikini area, ingrown hairs are the single most likely explanation. These show up as small red bumps, often with a visible pimple-like head. They can be sore to the touch and sometimes fill with white pus if the blocked follicle gets mildly infected. They typically appear on the outer labia or bikini line where hair grows thickest. Most clear up within a week or two without treatment.
Bartholin Gland Cysts
Two small glands sit near the vaginal opening, roughly at the 4 o’clock and 8 o’clock positions. These glands are normally pea-sized (about half a centimeter), but if their ducts get blocked, fluid backs up and forms a painless, round lump that can grow to 2 to 4 centimeters. A Bartholin cyst that stays small and doesn’t hurt requires no treatment at all. If it becomes infected and turns into an abscess, though, it swells rapidly, becomes very tender, and may need to be drained by a healthcare provider.
Epidermal Cysts
These firm, round, yellowish-white bumps form when skin cells get trapped beneath the surface. They’re most often found on the outer labia and can range from a few millimeters to several centimeters. They’re painless unless they become inflamed or infected. They sometimes stick around for months or longer but are completely benign.
Vestibular Papillomatosis
This one catches people off guard because it looks alarming but is actually a normal anatomical variation. It appears as clusters of soft, pink, finger-like projections on the inner labia or around the vaginal opening. Each tiny projection has its own separate base, they’re arranged symmetrically, and they don’t hurt or itch. Many people mistake these for genital warts, but they’re not caused by a virus and don’t need treatment.
How to Tell Warts From Normal Bumps
Genital warts caused by HPV are firm, skin-colored or slightly pigmented, and randomly scattered rather than neatly arranged. Their individual finger-like projections tend to fuse together at the base, unlike vestibular papillomatosis where each projection stands separate. Warts start small (1 to 2 mm) with a rough surface but can merge over time into larger clusters with a cauliflower-like texture. They can take anywhere from 3 weeks to 9 months to appear after exposure to HPV.
If you’re unsure whether what you’re seeing is a normal variation or a wart, a clinician can tell the difference quickly with a visual exam or, in some cases, a magnified inspection of the skin’s surface.
Signs That Point to an STI
Two sexually transmitted infections commonly cause bumps in this area, and they look quite different from each other.
Herpes (HSV) produces clusters of small, round blisters filled with clear fluid. Within a few days the blisters burst, leaving shallow sores that crust over with a yellowish-brown scab before healing. You’ll usually feel tingling, burning, or itching before the blisters appear, and the sores themselves can be painful. Some people also get a fever or swollen lymph nodes during a first outbreak. Symptoms typically show up 6 to 10 days after exposure.
Molluscum contagiosum creates small, firm, raised bumps that are distinctive because they often have a visible dip or dimple in the center. These spread through skin-to-skin contact, including sexual contact, and can also spread to other areas of your own body if you scratch or shave over them. They’re not dangerous, but they are contagious.
What You Can Safely Do at Home
For a bump that seems like an ingrown hair, a clogged pore, or a small painless cyst, warm soaks are the best first step. A sitz bath, where you sit in a few inches of warm water, helps draw out irritation and can encourage a clogged gland to open on its own. Keep the water at a comfortable warm temperature, around 104°F (40°C). You can do this three to four times a day for 15 to 20 minutes each session. Many Bartholin cysts and minor infections improve significantly within a few days of consistent sitz baths.
Keep the area clean and dry between soaks. Wear breathable cotton underwear and avoid tight clothing that creates friction. If you’ve been shaving or waxing, give the area a break until the bump resolves.
One thing you should never do: squeeze, pop, or try to drain a bump yourself. Puncturing a cyst or abscess with a needle or your fingers can push bacteria deeper into the tissue, cause a worse infection, and lead to scarring. This applies to every type of bump, not just cysts.
When a Bump Needs Medical Attention
Most bumps are harmless, but certain signs suggest you should get it looked at sooner rather than later:
- Rapid growth or increasing pain: A bump that doubles in size over a day or two, especially with worsening tenderness, may be forming an abscess.
- Pus or blood draining from the bump: This suggests infection.
- Fever or swollen glands: These are signs your body is fighting an infection that may need more than home care.
- Blisters that burst into open sores: This pattern is characteristic of herpes and benefits from antiviral treatment.
- A bump that persists for several weeks without changing: Even if it’s painless, a lump that doesn’t resolve on its own is worth having examined.
- Pain when urinating, unusual discharge, or a rash: These can indicate an STI that needs testing.
What to Expect at a Doctor’s Visit
If you do go in, the visit is usually straightforward. A visual exam is often enough for a clinician to identify common bumps like cysts, ingrown hairs, or warts. If herpes is suspected and a sore is present, they can swab the lesion for a test that detects the virus directly. This type of test is highly sensitive, especially when the sore is fresh. If no active sore is present, a blood test can check for antibodies to the herpes virus.
For a Bartholin cyst or abscess that’s large and painful, the provider may drain it in the office and place a small catheter to keep the duct open while it heals. For warts or molluscum, several removal options exist depending on the size and number of bumps. None of these visits are emergencies in most cases, but getting a diagnosis gives you a clear path forward instead of weeks of wondering.
