What is a corn on the foot?
You can get rid of a corn on your foot with medications, alternative remedies and treatments, and surgery.
Corns may be uncomfortable, but they grow to protect your foot from damage and can be easily treated. These are also called hyperkeratosis and are often caused by friction or pressure on the skin.
A corn is a hard, yellow lump of skin that usually grows on the feet. They grow because of stress and pressure on the skin, but are not considered a skin disease. However, sometimes they can develop infections and affect your daily activities.
Symptoms of corns
Symptoms of a hard corn on your feet may include:
They grow on the baby toe, on tops of the toes, on bony lumps, or on toe joints.
Soft corns are softer lumps in the skin, usually between the toes. Symptoms of soft corns may include:
- Soggy, soft skin between the toes
- Pain while walking
- Development between fourth and fifth toes
Soft corns are more prone to fungal or bacterial infections as the skin becomes soft and may open.
Causes of corns
Corns are caused by pressure or rubbing on the skin. Extra skin and keratin grows to protect against sores. As the skin and keratin build up, corns grow and can cause pain and difficulty walking.

- Bony lumps on your toes
- How you walk
- Poorly-fitting shoes
- High-heeled shoes
- Bone structure of your foot
Who can get corns
Poorly-fitting shoes are the most common cause of corns. People who wear shoes that are too tight or too small may develop corns. Corns also commonly develop on toes that have bony lumps, that curl under, or have a hammertoe deformity.
People with darker skin and older people could be more likely to develop corns. People who wear high heels or narrower shoes may also be more likely to develop corns.
Diagnosis for corns
To diagnose a corn, your doctor will examine your feet. They may also ask you questions about your shoes, your physical activity, and your medical history.
