The most common bump on the vulva is folliculitis, which can sometimes be related to hair removal with shaving or waxing — hello in-grown hairs! "Folliculitis is similar to a pimple, meaning an infection at the base of a hair follicle," Dr. Jessica Vaught, M.D., a gynecologist and director of minimally invasive surgery at Winnie Palmer Hospital for Women & Babies, tells Bustle. "This can happen very commonly and usually will resolve on its own." If it’s bothering you, and you notice it’s not going on away, speaking with your OB-GYN will help you find solutions for treatment.

Bartholin's Gland cysts can be painful bumps and are usually felt at the bottom of your sits-bones when sitting or walking. They are the most common cyst to occur in the vulva; the American Family Physician Journal cites 2% of women experiencing this kind of cyst at least once in their lifetime. The Bartholin's gland’s job is to secrete mucus, says Vaught. "If the gland become clogged, it will form a palpable lump that can grow as large as a golf ball." This can be evaluated by your gynecologist, and possible treatments include antibiotics and even drainage, if necessary.

Many conditions associated with skin can impact your underwear zone, Dr. Felice Gersh, M.D., OB0GYN, founder/director of the Integrative Medical Group and the author of PCOS SOS Fertility Fast Track, tells Bustle. “Bumps found on the vulva include the possibility of a type of skin cyst, like an epidermal inclusion cyst.” An inclusion cyst is one of the most common types, and it’s not caused by a blocked gland. It’s sometimes formed from trauma to the vulva skin, though it can just occur on its own, and is often very small.

Genital herpes usually presents as a sore or lesion. "Herpes is usually not silent, meaning the patients will usually be symptomatic with burning, pain, and itching," Vaught says. "Genital herpes can start as a small bump, but then it will develop into a blister and then an ulcer. This can be treated with an anti-viral medication, but needs to be evaluated by your doctor." You might be imagining scary pictures of boils on your vulva and labia, but herpes is incredibly common, and nothing to feel ashamed of. Don't be afraid to speak up if you have these symptoms, and discuss with your doctor the best treatment plan for you.

Caused by the human papillomavirus (HPV), genital warts are cauliflower-like lesions that can grow on the labia, inside the canal, on the cervix, or around the anus. "They are usually painless, but can have itching and burning," Vaught says. "Both herpes and genital warts are considered sexually transmitted diseases." As with herpes, genital warts are also nothing to be ashamed of. HPV is the most common sexually transmitted infection (STI), according to the CDC, with 79 million Americans having the infection. If you notice these symptoms, consult your doctor who can help you find a solution you're comfortable with.

“Moles can develop on the vulva and present as pigmented bumps,” Dr. Gersh says. This could be a vulvar melanoma, or tiny cancer, or it could simply be a new mole; many people have moles or freckles around their vulvar region that turn out to be benign. If you notice a new raised brown mole, though, it’s a good idea to get it checked out.

Varicose veins can also appear as bluish, raised bumps, says Vaught. These bumps are usually painless, but they can occasionally cause itching and may bleed. They are also very common in pregnant people — according to The International Journal of Women’s Health, it is estimated that 18 to 22% of pregnant people have varicose veins they develop around their vulva. Treatment is not usually necessary for this type of bump, and some doctors will recommend applying ice packs to the affected area. In more severe cases, doctors can inject varicose veins with a solution to help them close, and fade.

Skin tags, or small protruding flaps of extra skin, are very common pubic area bumps. "They are harmless, but sometimes cause discomfort secondary to them rubbing on other tissues," Vaught says. "They can be removed surgically if they are causing discomfort."

The skin of the vulva is very sensitive, and can suffer from contact dermatitis if it’s irritated. “Allergic reactions can sometimes cause irritation and bumpiness in vulvar skin,” Dr. Gersh says. In this case, the bumps will likely be accompanied by itchiness and irritation. Allergies can be caused by anything from new laundry detergents to body washes.

Molluscum Contagiosum are tiny, flesh-colored bumps with a white dimple in the middle are a very common, but highly contagious skin disease caused by a virus. "Shared towels or clothing, a sweaty bike seat at the gym, wrestling and other mat sports, and sexual contact is how this virus is spread," Dr. Shannon Klingman, M.D., an OB/GYN, tells Bustle. Thankfully, molluscum contagiosum is usually harmless and tends to go away on its own. If it becomes a concern to you, though, your doctor can freeze them away using cryotherapy.

These are whiteheads or deeper pimples where the center forms a black, waxy core. "Astringents used for facial acne on a cotton ball can be used to help heal the area and prevent the return of one after you have removed it," Klingman says.

The sweat glands around the vulva can get infected, and that can result in bumps. “Infections of sweat glands can form, and when recurrent, can indicate a condition called hidrandenitis suppurativa,” Dr. Gersh says. The bumps will be painful to the touch or when you move, and may also get inflamed. They’re not simple pimples and will need medical treatment.

A lump in your vulva can possibly be a tumor, but that doesn’t mean it’s malignant or cancerous. One possible cause is a neuroma, a kind of pinched nerve that will be quite painful, but can be treated, Dr. Gersh says, adding that tumors and cancers that take the shape of bumps in that area are very rare. Vulvar cancers only account for 0.6% of all cancers in women in the U.S., per Johns Hopkins Medicine.
