Most lumps in the vaginal or vulvar area are harmless and resolve on their own or with simple home care. Cysts, ingrown hairs, and blocked glands account for the vast majority of these bumps. Still, finding one can be alarming, so knowing what you’re likely dealing with and when it needs medical attention makes a real difference.
The Most Common Causes
The vulvar and vaginal area has hair follicles, oil glands, and specialized lubricating glands, all of which can become blocked, irritated, or infected. Where the lump is and what it feels like narrows down the possibilities considerably.
Bartholin’s Cyst
The Bartholin’s glands sit on either side of the vaginal opening and produce fluid that helps with lubrication. When one of these glands gets blocked, fluid backs up and forms a painless, round lump. About 2% of women develop a Bartholin’s cyst or abscess in their lifetime, making it one of the most common vulvar lumps. These cysts can range from pea-sized to golf ball-sized. A small one may cause no symptoms at all. If the cyst becomes infected and turns into an abscess, it swells quickly, becomes very tender, and the skin over it may look red or feel warm.
Ingrown Hair or Folliculitis
If you shave, wax, or wear tight clothing, an ingrown hair is a very likely explanation. These look like a small, tender bump with a visible hair trapped under the skin, sometimes with a white or yellow center similar to a pimple. Folliculitis, which is inflammation of one or more hair follicles, creates a similar appearance and can look like a cluster of razor bumps or acne. These are most common on the outer labia and bikini line where hair grows.
Skene’s Gland Cyst
The Skene’s glands sit on either side of the urethral opening (where urine comes out), slightly higher up than the Bartholin’s glands. When one gets blocked, it forms a small, smooth lump you can feel just under the skin. Most Skene’s gland cysts are about the size of a pea, under half an inch across. In rare cases they can grow to 3 inches, but this is uncommon.
Vaginal Inclusion Cyst
These are the most common type of vaginal wall cyst. They develop when skin cells get trapped beneath the surface, often at the site of a previous injury like childbirth, an episiotomy, or surgery. They tend to show up in women in their 30s and 40s and are typically painless. Many women never even notice them; they’re frequently discovered during a routine pelvic exam.
Sebaceous Cyst
Oil glands in the vulvar skin can become blocked and form a firm, round lump that moves slightly when you press on it. These tend to grow slowly and are painless unless they get infected, at which point they become red, swollen, and sore.
Lumps Caused by Infections
Some bumps in this area are caused by viral infections that spread through skin-to-skin contact.
Genital warts, caused by certain strains of HPV, are typically small and flat, with a rough texture. They can be flesh-colored, brown, or pink. Left untreated, they sometimes grow larger and develop a cauliflower-like appearance, particularly in people with weakened immune systems. They can appear as a single bump or multiply into clusters.
Molluscum contagiosum creates firm, dome-shaped bumps that are usually 2 to 5 millimeters across, about the size of a pencil eraser or smaller. They tend to be white or flesh-colored and may have a small dimple in the center. Unlike warts, molluscum bumps don’t usually grow or change once they appear, and they can be filled with clear or white fluid. Both conditions are treatable, and a clinician can tell the difference with a visual exam.
What You Can Do at Home
For a painful lump that seems like a cyst, an ingrown hair, or a blocked gland, a sitz bath is the most effective first step. Fill a bathtub with a few inches of warm water (around 104°F or 40°C is ideal) and soak for 15 to 20 minutes. Doing this three to four times a day can help draw out fluid, soften the skin over a cyst, reduce swelling, and encourage a blocked gland to drain on its own.
Beyond sitz baths, keep the area clean and dry. Avoid squeezing, popping, or trying to lance the lump yourself. This almost always makes things worse by pushing bacteria deeper or causing scarring. Wear loose, breathable cotton underwear and avoid shaving the irritated area until it heals. Over-the-counter pain relievers can help with discomfort while you wait for the lump to resolve.
Many small cysts and ingrown hairs clear up within a week or two with this approach alone.
Signs That Need Medical Attention
Some lumps do need a professional evaluation. See a healthcare provider if you notice any of the following:
- Rapid growth or increasing pain. A cyst that becomes very swollen, hot, or painful over a day or two may have become an abscess that needs to be drained.
- Fever or spreading redness. These suggest the infection is spreading beyond the lump itself.
- A lump that doesn’t go away after two to four weeks of home care, even if it’s painless.
- Multiple bumps or wart-like growths. Clusters of rough or dome-shaped bumps should be evaluated for viral causes.
- A hard, fixed lump that doesn’t move under the skin. While vulvar cancer is rare, especially in younger women, a firm lump that feels attached to deeper tissue and doesn’t change should always be checked.
- Any new lump if you’re over 40. The likelihood of benign cysts remains high, but the threshold for getting checked should be lower.
What Happens at a Medical Visit
A provider can usually identify the type of lump with a visual and physical exam alone. In some cases they may swab for infection or take a small tissue sample to rule out anything unusual.
For a Bartholin’s cyst or abscess that’s large (generally 3 centimeters or bigger) or keeps coming back, the standard treatment is a small in-office procedure. The provider makes a tiny incision to drain the fluid and may place a small balloon catheter, about the size of a short straw, inside the opening. This stays in place for several weeks and allows the gland to form a new permanent drainage channel so the cyst is less likely to return. The procedure itself is quick, and most women return to normal activities within a day or two.
Vaginal inclusion cysts that cause discomfort can be surgically removed through a minor procedure with low recurrence rates. Many, though, are simply monitored if they’re not causing problems.
For warts or molluscum, treatment options include topical solutions applied at the clinic or freezing the bumps off. Both conditions can take several visits to fully clear, but neither is dangerous.
Lumps That Keep Coming Back
Recurrent lumps in the same spot usually point to a gland that keeps getting blocked or a hair follicle that’s chronically irritated. Bartholin’s cysts recur in a meaningful percentage of women even after drainage. If a cyst returns more than twice, a provider may recommend a more permanent procedure to create a lasting drainage opening or, in rare cases, to remove the gland entirely.
For recurring ingrown hairs or folliculitis, switching your hair removal method often helps. Laser hair removal reduces ingrown hairs significantly for people who get them repeatedly. If you prefer shaving, using a single-blade razor, shaving in the direction of hair growth, and applying a gentle exfoliant between shaves can cut down on blocked follicles.
