10 Possible Foot Bump Causes

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

Wart

Warts, also called common warts or verrucae, are small, rough, rounded growths on the top layer of the skin. They may appear alone or in clusters. Common warts are caused by the human papillomavirus (HPV) and are contagious through direct contact. They may spread from one place on the body to another simply through touch.

Corn

A corn is a hard, thick layer of skin that develops when the skin experiences lots of friction and pressure. A corn may cause discomfort, but is of no big concern.

Rarity: Uncommon

Top Symptoms: thickened skin on the foot with visible lines, foot bump with lines through the thickened skin, painful thickened skin, skin thickening

Symptoms that always occur with corn: thickened skin on the foot with visible lines

Urgency: Self-treatment

Morton neuroma

Morton neuroma, also called by the older name Morton's neuroma, is a thickening of fibrous tissue in the ball of the foot. This tissue encapsulates the nerve leading to the third and fourth toes. It is not actually a tumor of the nerve, as the name suggests.

The thickening is caused by years of trauma, irritation, and/or compression to the feet. High-heeled shoes, especially if narrow or tight, are a common cause. The condition is most often seen in women over age 45.

Symptoms include burning pain in the ball of the foot, especially with walking or running. The condition will not heal on its own and can lead to chronic foot pain.

Diagnosis is made through physical examination of the foot with simple range of motion exercises, and sometimes x-ray.

Treatment includes changing to better-fitting shoes that do not compress the nerve; using orthotics in the shoes to take more pressure off of the nerve; and in some cases the use of corticosteroid injections.

Rarity: Rare

Top Symptoms: foot numbness, pain in the sole of the foot, pain when touching the foot, pain in both feet, foot injury

Urgency: Self-treatment

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

Dermatofibroma

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, ...

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
