9 Possible Lump On One Side Of The Groin Causes

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

Groin hernia

A groin hernia, also called an inguinal hernia, means that a structure in the lower abdomen – a loop of intestine or a section of fat – has pushed through the muscles of the abdominal wall. This creates a bulge, or hernia, that can be seen and felt in the groin.

A hernia is caused by a weak spot in the abdominal wall muscles, which can separate under heavy lifting or repeated straining. The weakness may be inherited or may be from previous surgery, injury, or pregnancy.

Symptoms include a bulge low down in the abdomen, most visible when the person stands; and pain in the bulge with any strain on the abdominal muscles, such as lifting a heavy object or bending over.

A hernia will not heal on its own. There is the risk of serious complications if the blood supply to the herniated organ becomes reduced or cut off.

Diagnosis is made through physical examination and x-ray or CT scan.

A small hernia may need no treatment. A larger one can be repaired with surgery.

Rarity: Uncommon

Top Symptoms: pain in the lower right abdomen, pain in the lower left abdomen, groin pain, testicle pain, groin lump

Urgency: Primary care doctor

Groin abscess

A groin abscess is caused by an infection of the skin or area right under the skin. The infection is typically caused by a bacteria, which your body reacts to by creating a ball of inflammation around the bacteria.

Rarity: Common

Top Symptoms: groin pain, constant groin lump, lump on one side of the groin, painful lump in one side of the groin, hard groin lump

Symptoms that always occur with groin abscess: lump on one side of the groin, constant groin lump

Urgency: Primary care doctor

Enlarged lymph nodes in the groin

Enlarged lymph nodes occur when the node becomes larger as it fills with inflammatory cells. This often is a result of an infection but can occur without a known cause.

Rarity: Common

Top Symptoms: groin lump, movable groin lump

Symptoms that always occur with enlarged lymph nodes in the groin: groin lump

Symptoms that never occur with enlarged lymph nodes in the groin: fever, unintentional weight loss, hard groin lump

Urgency: Phone call or in-person visit

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

Groin hernia requiring a doctor's examination

A groin hernia, or inguinal hernia, is the protrusion of an organ or other tissue – usually a loop of intestine – through a tear or weakness in the lower abdominal muscles. It can be easily felt beneath the skin, especially when the person is standing upright.

A groin hernia is most often found in men doing any kind of heavy lifting, though women can also be affected.

Symptoms include aching, burning groin pain with a sense of heaviness. The pain may be severe, especially on exertion. There may be an abdominal bulge that disappears when the patient lies on his/her back.

It is important to have a suspected inguinal hernia examined by a medical provider for possible treatment. A hernia can become strangulated, which means that its blood supply is cut off. A strangulated hernia is a medical emergency.

Diagnosis is made through patient history, physical examination, and sometimes ultrasound.

Treatment usually involves surgical repair of the hernia, although a small hernia may simply be monitored for any change.

Rarity: Rare

Top Symptoms: nausea, nausea or vomiting, fever, groin pain, groin lump

Urgency: Emergency medical service

Indirect hernia

Hernias occur when an organ protrudes through part of the abdominal/pelvic wall that normally contains it. Indirect hernias are located near the groin and occur when abdominal contents, such as the intestines, pass through an opening into a channel called the inguinal canal.

Lipoma

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

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

Lymphangitis

Lymphangitis is a condition resulting in inflamed lymphatic vessels due to an infection. The lymphatic system runs throughout the body and consists of both nodes and these vessels. The nodes produce lymph — the clear fluid that bathes and nourishes the organs and other tissues — while the vessels cir...
