Butt Bump Symptoms

A bump on the butt may be a new development or a chronic condition — either way, many people who experience similar symptoms are often embarrassed about seeing a medical professional for an evaluation. While this is understandable, you should know that you are not alone and it is important to monitor the bump and seek care as soon as you are concerned.

Common accompanying symptoms of a butt bump are

In addition to the butt bump, you may also experience symptoms that include:

Bumps or lesions on the buttocks are relatively common, and usually do not signal immediately life-threatening conditions [3]. However, it is important to follow-up with a healthcare professional about your condition in order to properly treat, prevent recurrence and manage complications.

Butt Bump Causes

Many of the causes of butt bumps are dermatologic in nature and affect aspects of the skin including hair follicles. The skin is the largest and often heaviest organ of the body and has multiple components. The skin has three layers known as:

  • Epidermis: This is the outermost layer of the skin visible to the eye. It contains specialized cells responsible for pigmentation of the skin (melanocytes), protecting the skin (Langerhans cells) and allowing the skin to feel pressure (Merkel cells).
  • Dermis: This is the middle layer of the skin. It contains a network of tough but elastic collagen fibers that make the skin strong but also stretchy and a network of nerves and blood vessels that allow passage of nutrients and oxygen. The dermis also contains sweat glands.
  • Subcutis/Subcutaneous layer: This is the deepest layer of skin which contains fat and connective tissue. It acts as a shock absorber and insulator and produces hormones like vitamin D when the skin is exposed to sunlight.

See this image here for a visual representation of the layers of the skin.

Many of the cases of butt bumps affect these components of skin and can be grouped into the following categories:


Inflammatory causes that can result in a butt bump include the following.

  • Infectious: The skin is home to a bacterium known as Staphylococcus aureus (Staph). Although it is a normal component of the skin flora, it is the leading cause of human bacterial infection and can result in bumps and lumps throughout the body including the butt. Staphylococcus aureus can enter the skin via small lesions or cuts and result in painful abscesses filled with pus [4].
  • Cysts: Cysts are sacs that can be filled with fluid, air, or other material that can form in any part of the body. Cysts that form in the epidermis of the skin often present as skin-colored nodules — see image here. Cysts can also be related to the hair follicles around the buttocks area and can become inflamed and infected. These cysts are known as pilonidal cysts.


In general, any growth is the result of cells dividing and growing uncontrollably. Cells in any part of the body — fat, blood vessels, soft tissue, etc. — can grow in this abnormal fashion. These abnormal cells can accumulate to form a noticeable lump or bump in the body part affected. These growths (also known as tumors or neoplasms) can be benign (non-threatening) or malignant (life-threatening).

  • Vascular: Growths that result from the vasculature and blood vessels of the body are called angiomas or pyogenic granulomas [3]. They are often red and dome-shaped and can bleed copiously with trauma.
  • Fat/soft tissue: Growths of the fat and soft tissue of the skin are known as lipomas and often present as soft, round or oval painless nodules. They most commonly occur on the back and upper extremities but can appear in other locations including the butt.


Environmental causes can be related to lifestyle habits or repeated exposure of the skin.

  • Friction/pressure: Friction or pressure from common things such as tight or restrictive clothing, long periods of sitting, or skin rubbing against skin is often a factor in the development of bumps or lumps on the skin, especially related to hair follicles.
  • Trauma: Minor traumatic injury to the butt area can result in bruising or irritation that may manifest as bumps or lumps in the area.

8 Possible Butt Bump Conditions

The list below shows results from the use of our quiz by Buoy users who experienced butt bump. This list does not constitute medical advice and may not accurately represent what you have.

Skin cyst

A cyst is a small sac or lump, filled with fluid, air, fat, or other material, that begins to grow somewhere in the body for no apparent reason. A skin cyst is one that forms just beneath the skin.

It's believed that skin cysts form around trapped keratin cells – the cells that form the relatively tough outer layer of the skin.

These cysts are not contagious.

Anyone can get a skin cyst, but they are most common in those who are over age 18, have acne, or have injured the skin.

Symptoms include the appearance of a small, rounded lump under the skin. Cysts are normally painless unless infected, when they will be reddened and sore and contain pus.

Diagnosis is made through physical examination. A small cyst can be left alone, though if it is unsightly or large enough to interfere with movement it can be removed in a simple procedure done in a doctor's office. An infected cyst must be treated so that the infection does not spread.

Rarity: Common

Top Symptoms: skin-colored armpit bump, marble sized armpit lump, small armpit lump

Symptoms that always occur with skin cyst: skin-colored armpit bump

Urgency: Wait and watch

Boil (furuncle)

A furuncle, also called a boil, is infection of a hair follicle. The infection forms under the skin at the root of the hair and may occur anywhere on the body.

The infection is caused by bacteria, most often Staphylococcus aureus or "staph." Irritation caused by clothes or anything else rubbing the skin can cause the skin to break down and allow bacteria to enter.

Staph bacteria are found everywhere. Frequent and thorough handwashing, and otherwise maintaining cleanliness, will help to prevent its spread.

Most susceptible are those with a weakened immune system; diabetes; and other skin infections.

Symptoms include a single bump under the skin that is swollen, painful, and red, and contains pus.

It is important to treat the boil, since infection can spread into the bloodstream and travel throughout the body.

Diagnosis is made through physical examination and sometimes fluid sample from the boil.

Treatment may involve incision and drainage of the infection, followed by creams to apply to the site of the boil and/or a course of antibiotic medicine.

Rarity: Uncommon

Top Symptoms: pink or red facial bump, small facial lump, painful facial bump, marble sized facial lump, constant skin changes

Symptoms that always occur with boil (furuncle): pink or red facial bump

Symptoms that never occur with boil (furuncle): fever

A dermatofibroma is a common skin growth that usually appears on the lower legs, but may appear anywhere on the body. These growths are benign (noncancerous). Dermatofibromas are most common in adults and are rarely found in children.

Symptoms include a hard, raised growth that is red, pink, ...

Pimples are also called comedones, spots, blemishes, or "zits." Medically, they are small skin eruptions filled with oil, dead skin cells, and bacteria.

Pimples often first start appearing at puberty, when hormones increase the production of oil in the skin and sometimes clog the pores.

Most susceptible are teenagers from about ages 13 to 17.

Symptoms include blocked pores that may appear flat and black on the surface, because the oil darkens when exposed to the air; blocked pores that appear white on the surface because they have closed over with dead skin cells; or swollen, yellow-white, pus-filled blisters surrounded by reddened skin.

Outbreaks of pimples on the skin can interfere with quality of life, making the person self-conscious about their appearance and causing pain and discomfort in the skin. A medical provider can help to manage the condition, sometimes through referral to a dermatologist.

Diagnosis is made through physical examination.

Treatment involves improving diet; keeping the skin, hair, washcloths, and towels very clean; and using over-the-counter acne remedies.

Rarity: Common

Top Symptoms: pink or red facial bump, small facial lump, painful facial bump, marble sized facial lump

Symptoms that always occur with pimple: pink or red facial bump

Lipoma is a word that translates as "fatty tumor," but a lipoma is not cancer. It is simply a growth of fat between the muscle layer and the skin above it.

The exact cause is not known. The condition does run in families and is associated with other unusual syndromes such as adiposis dolorosa, which is similar. Lipomas most often appear after age 40.

Symptoms include a soft, easily moveable lump beneath the skin, about two inches across. A lipoma is painless unless its growth is irritating the nerves around it. They are most often found on the back, neck, and abdomen, and sometimes the arms and upper legs.

It is a good idea to have any new or unusual growth checked by a medical provider, just to make certain it is benign.

Diagnosis is made through physical examination, biopsy, and imaging such as ultrasound or CT scan.

Most of the time, treatment is not necessary unless the lipoma is unsightly or is interfering with other structures. It can be removed through surgery or liposuction.

Rarity: Uncommon

Top Symptoms: skin-colored groin bump, marble sized groin lump, small groin lump

Symptoms that always occur with lipoma: skin-colored groin bump

Urgency: Wait and watch

Mole on the butt

Moles are growths on the skin. They happen when pigment cells in the skin, called melanocytes, grow in clusters.

Rarity: Uncommon

Top Symptoms: unchanged butt bump, black or brown butt bump, small butt lump, uniformly black/brown butt bump, butt bump's smooth border

Symptoms that always occur with mole on the butt: unchanged butt bump, black or brown butt bump

Urgency: Wait and watch


Blackheads are caused by hair follicles becoming clogged with oil & dead skin cells. When the clogged pore is open to the air, the air turns the outermost layer black through oxidation.

Rarity: Common

Top Symptoms: small facial lump, black or brown facial bump

Symptoms that always occur with blackhead: small facial lump, black or brown facial bump

Urgency: Self-treatment

Skin abscess

A skin abscess is a large pocket of pus that has formed just beneath the skin. It is caused by bacteria getting under the skin, usually through a small cut or scratch, and beginning to multiply. The body fights the invasion with white blood cells, which kill some of the infected tissue but form pus within the cavity that remains.

Symptoms include a large, red, swollen, painful lump of pus anywhere on the body beneath the skin. There may be fever, chills, and body aches from the infection.

If not treated, there is the risk of an abscess enlarging, spreading, and causing serious illness.

Diagnosis is made through physical examination.

A small abscess may heal on its own, through the body's immune system. But some will need to be drained or lanced in a medical provider's office so that the pus can be cleaned out. Antibiotics are usually prescribed.

Keeping the skin clean, and using only clean clothes and towels, will help to make sure that the abscess does not recur.

Rarity: Common

Top Symptoms: rash with bumps or blisters, red rash, red skin bump larger than 1/2 cm in diameter, pus-filled rash, rash

Symptoms that always occur with skin abscess: rash with bumps or blisters

Urgency: Primary care doctor

Butt Bump Treatments and Relief

When to see a doctor

The causes of butt bumps are varied and treatment is dependent on the specific cause, making it important to see your doctor. Many of the treatments are surgical in nature and involve physical removal of the bump. Treatment for a bump is often only necessary if it is causing you stress or worry; however, having the bump removed for primarily cosmetic reasons is typically welcome. Surgical options include [3]:

  • Cryosurgery: The application of extreme cold to destroy and remove diseased tissue.
  • Electrodesiccation: The use of an electric current to remove skin lesions.
  • Shave excision: This is the use of a sharp razor with or without an electrode to feather the edges of a lesion to make it smaller or less noticeable.
  • Scissors: At times the solution is to simply cut off the lesion/bump with surgical scissors.

If the butt bump is associated with an infection, your physician will prescribe appropriate antibiotics to treat the condition and prevent complications.


Some skin bumps are hereditary in nature and cannot be prevented. However, there are things you can do at home in order to reduce the likelihood of developing some types of butt bumps such as:

  • Wearing loose, not tight-fitting clothes
  • Proper personal hygiene: Such as showering and properly drying oneself every day
  • Maintaining a healthy weight
  • Avoiding activities that cause excessive rubbing of the skin

FAQs About Butt Bump

Can my butt bump be removed?

Yes, a butt bump can usually be removed. There are a variety of surgical modalities that can be performed in an office (versus an operating room); however, it is important to discuss indications of removal with your physician as sometimes bumps in this area do not require treatment.

Will my butt bump go away on its own?

Usually, butt bumps and skin conditions do not go away without some sort of treatment, whether it involves surgery or antibiotics. If your butt bump is persistent and bothersome you should consult a medical professional.

Will a butt bump interfere with my daily activities?

Some butt bumps such as pilonidal cysts and abscesses can cause pain and make it very difficult and uncomfortable to sit down or lie on your back. If these bumps become infected or inflamed, the pain can be exacerbated and involve redness, swelling, and drainage.

What is a pilonidal cyst?

A pilonidal cyst is a fluid-filled sac that develops above the crease where the buttocks come together. These cysts are often related to friction or pressure on the hair follicles in the area that become pushed into the skin and inflamed.

What is hidradenitis suppurativa?

Hidradenitis suppurativa is a condition that results in swollen, painful, often red bumps that develop in dark/damp areas of the body such as the armpits, groin, and under the breasts in women [5]. They are extremely painful and can limit movement. They often have an odor and can drain pus or blood depending on the severity. This is a chronic condition that requires appropriate long-term medical care.

Questions Your Doctor May Ask About Butt Bump

To diagnose this condition, your doctor would likely ask the following questions:

  • What color is the bump?
  • Is the bump painful to touch?
  • Any fever today or during the last week?
  • Do you have a rash?

The above questions are also covered by our A.I. Health Assistant.
