Chances are that you have experienced, or at least heard of, a callus on your hand or foot, but have you heard of something called a corn? If you have experienced a hard, sore and perhaps tender spot on your foot when you walk and bear weight, you may have a corn. But what exactly are they?
What is a Corn?
Corns, also known as Clavi, are quite common skin lesions that form from repeated friction and pressure to a specific area. The most common areas we see clavi are on the tops of the feet as well as the soles and sides of the feet. They may also form in between the toes as well.
The presentation consists of a thick, hardened skin lesion that may be raised and firm. Because they are often found on weight-bearing areas, they may be raised and tender when pressed or walked upon causing a nuisance during weight bearing activities, such as your daily walking or running.
What is the difference between a Corn and a Callus?
A callus may also form from repeated friction to an area, especially pressure points such as the heels and palms (think running and weightlifting), however they may be larger and rougher than a corn. Calluses also tend not to be painful or sore. A corn is a deeper type of callus, but by contrast, clavi (or corns) tend to be smaller and more well-defined than a callus after appearing. You may also notice that there is a central hard “core” that is visible after paring or filing the lesion down. Corns may also be swollen and red at times. Some people notice that having a corn may feel as though they are walking on a pebble because of the discomfort they experience.
Methods for Preventing Corns
Since we know that clavi are a direct result of pressure and friction to a specific area, most commonly the foot, the best type of prevention is to reduce the amount of friction and pressure to that area. Here are some things that you can do to reduce your risk of developing a corn, and to alleviate some of the discomfort you may be experiencing if you have one:
- Ensure that your shoes fit properly. There should be enough room in the toe box for your toes to be able to wiggle freely. However, make sure the shoe is not too big as this can also contribute to excessive friction.
- Choose shoes that promote an even distribution of weight, such as those with low heels and adequate cushioning.
- Seek treatment if you presently have foot deformities such as a bunions or hammertoes as this can cause uneven weight distribution as well as friction.
- Practice good foot hygiene. Wash and inspect your feet once daily. Use pumice stones to exfoliate. Keep your toenails trimmed and moisturize your feet to prevent dryness and cracking.
Is There an Effective Treatment for Corns?
Once you suspect that you have a corn, you may wonder if it can be treated. While we know that prevention is the best way to manage these, there are a few things that can be done if you are experiencing a significant amount of pain or discomfort.
- You may seek evaluation with a dermatology provider or podiatrist.
- You may gently file the lesion with a pumice stone or emery board to smooth it out and remove some of the skin.
- If you are not pregnant, you may use a moisturizer with salicylic acid, urea, or ammonium lactate to help soften the skin.
- Purchase protective adhesive pads or barrier dressings to reduce the amount of pressure and friction.
- In severe cases, podiatrists can remove them surgically or prescribe custom orthotics for your shoes to even out weight distribution during walking to alleviate pain and prevent recurrence or worsening.
If you are uncertain about whether you have a corn, you may consider scheduling a consultation with The Derm NP for evaluation.
