Recurring bumps in the vulvar and vaginal area are extremely common, and most of the time they’re caused by something benign like clogged pores, ingrown hairs, or normal anatomical features you’re only now noticing. That said, some causes do need treatment, and the “keeps happening” part of your question matters. Figuring out whether your bumps are harmless, infection-related, or tied to a chronic skin condition depends on what they look like, where they appear, and what other symptoms come with them.
Normal Anatomy That Looks Like Bumps
Before assuming something is wrong, it’s worth knowing that the vulva naturally has small bumps. Fordyce spots are tiny white, yellowish, or skin-colored dots caused by oil glands sitting close to the skin’s surface. Between 70% and 80% of adults have them. They’re typically 1 to 3 millimeters across (about the size of a sesame seed or smaller), and they can appear in clusters of 50 or more. They are not contagious and not an STI.
Another common find is vestibular papillomatosis, which looks like soft, finger-like projections lining the inner labia and vaginal opening. These are sometimes mistaken for genital warts, but the key difference is symmetry: vestibular papillomatosis appears evenly on both sides, and each tiny projection has its own separate base. Genital warts, by contrast, tend to fuse together at their base, feel firmer, and appear randomly rather than in a neat pattern. Vestibular papillomatosis is a completely normal variant and doesn’t need treatment.
Ingrown Hairs and Folliculitis
If your bumps tend to appear after shaving, waxing, or any hair removal, ingrown hairs are the most likely culprit. When a hair curls back into the follicle instead of growing outward, it irritates the surrounding skin and creates a red, tender, sometimes pus-filled bump that can look a lot like a pimple or even a herpes sore. These bumps are more common in people who shave, especially in areas with coarse or curly hair.
Folliculitis is the broader term for inflamed or infected hair follicles. It can be triggered by friction from tight clothing, sweat, or bacteria getting into freshly shaved skin. The bumps are usually superficial and heal on their own within a week or two. If you notice them recurring in a predictable pattern tied to your grooming routine, switching to a gentler hair removal method or giving the area a break from shaving is often enough to stop the cycle.
Cysts That Come and Go
Cysts are a major reason bumps feel like a recurring problem. The most common type on the vulva is an epidermal inclusion cyst, which forms when skin cells get trapped beneath the surface. These show up as firm, round, yellowish-white lumps, most often on the outer labia. They can range from a few millimeters to several centimeters and sometimes drain or shrink, only to fill back up again later, creating the impression of a bump that “keeps coming back.”
Bartholin’s cysts form specifically near the vaginal opening, where the Bartholin’s glands sit on either side. These glands produce lubricating fluid, and when their ducts get blocked, a soft, usually painless lump develops on one side. A small Bartholin’s cyst can go unnoticed. A larger one can make walking, sitting, or sex uncomfortable. If the cyst becomes infected and turns into an abscess, you’ll likely notice significant pain, tenderness, and possibly fever. Bartholin’s cysts tend to occur on one side at a time and can recur in the same spot.
Vestibular gland cysts are another possibility. These are soft, smooth, translucent bumps found on the inner labia, filled with clear mucin. They range from 2 to 30 millimeters and are benign.
Sexually Transmitted Infections
STIs are an understandable concern when bumps keep appearing. The two most relevant are genital herpes and HPV (genital warts), and they look quite different from each other.
Genital Herpes
Herpes bumps typically start with a tingling or burning sensation in a specific spot before anything is visible. Within a day or two, a cluster of small blisters appears. These blisters break open into red, painful sores that crust over and heal. The defining features are pain, clustering, and recurrence in the same area. Over 1 in 5 adults aged 15 to 49 worldwide are living with genital herpes, so it is far more common than most people realize. HSV-2, the type most associated with genital outbreaks, accounts for about 90% of symptomatic episodes and is substantially more likely to cause repeat flare-ups than HSV-1. Outbreaks tend to become less frequent and less severe over time, but the virus stays in the body permanently.
Genital Warts (HPV)
Genital warts caused by HPV look like small, skin-colored, raised or flat bumps. They can have a rough, cauliflower-like texture and are usually painless. Unlike herpes, they don’t blister, burn, or cluster in the same way. Warts can resolve on their own within a year, but they can also persist or multiply. Even after treatment, recurrence is common, particularly in the first three months. Most warts respond to treatment within about three months, and options include topical creams you apply at home or in-office procedures like freezing or surgical removal.
Molluscum Contagiosum
Molluscum is a viral infection that produces small, firm, pearl-like bumps, usually 2 to 5 millimeters across. The signature feature is a tiny dimple or indent in the center of each bump. They’re painless and spread through skin-to-skin contact. In adults, they often appear in the genital area and can be confused with warts or pimples. Molluscum bumps can persist for months and spread to new spots by scratching or touching, which is why they seem to “keep coming.”
Chronic Skin Conditions
If your bumps don’t match any of the descriptions above and instead involve patches of thickened, whitened, or eroded skin that persists for weeks or months, a chronic inflammatory condition could be responsible. Lichen sclerosus causes thinning, white patches on the vulva that can become itchy, fragile, and painful. Lichen planus tends to affect mucous membranes and can cause erosions or purplish, raised patches both on the vulva and inside the vagina, sometimes also affecting the mouth. Both conditions are driven by the immune system, not by infections, and both are chronic. They require ongoing management, typically with prescription-strength steroid ointments, and regular monitoring because both carry a small increased risk of vulvar skin cancer over time.
How Doctors Figure Out the Cause
A visual exam is often enough to identify common causes like ingrown hairs, Fordyce spots, or Bartholin’s cysts. For anything uncertain, a biopsy is the definitive way to diagnose a vulvar bump. Doctors will typically recommend a biopsy for bumps that grow quickly, ulcers that last longer than a month, lesions that bleed, or any bump that hasn’t responded to treatment. For suspected herpes, a swab of an active sore can confirm the diagnosis. HPV-related warts are usually diagnosed by appearance alone.
One clinical tool worth knowing about is the acetic acid test, where a 5% vinegar solution is applied to the skin for two to three minutes. Abnormal areas turn white. This test is very sensitive (catching 97% of high-grade abnormalities) but not very specific, meaning it can flag things that turn out to be harmless. A negative result, however, is highly reassuring, with a 98% negative predictive value for serious vulvar lesions.
Why They Keep Coming Back
The recurrence piece is what frustrates most people. The reason depends entirely on the cause. Ingrown hairs recur because you keep removing hair. Epidermal cysts recur because the sac lining stays in the skin even after the cyst drains. Herpes recurs because the virus lives permanently in nerve cells and reactivates periodically, often triggered by stress, illness, or hormonal changes. Genital warts recur because HPV can persist in surrounding skin cells even after visible warts are removed. Bartholin’s cysts recur because the underlying gland duct remains prone to blockage.
In other words, “keeps happening” doesn’t necessarily mean something is getting worse. It often just reflects the natural behavior of whatever is causing the bumps in the first place. Identifying the specific cause is the most useful step, because it tells you whether the pattern is expected, whether treatment can reduce flare-ups, and whether any further workup is needed.
