A corn is a small, round area of hard, dead skin that can cause significant pain when pressed on, making walking very uncomfortable.
A corn is similar to a callus in that it is a thickened area of dead skin that is caused by pressure or friction. Unlike a callus that spreads over the surface of an area of the skin and can cover the entire heels, corns are much smaller, measuring anywhere between 2mm and 20mm, and move deeper into the skin. Specifically, corns are actually conical (cone-like) in shape, with the widest end of the cone being visible as a circular shape on the outside of the skin. Their shape means that corns are typically much more painful when pushed upon or walked on if they’re present in a weight bearing area, like on the ball of the foot, or an area that directly pushes against shoes as you walk, like on the outside of the big toe.
There are several types of corns that can develop on the feet:
You may suspect a corn if you notice:
It is also very common for corns and calluses to occur together, given they have the same initial cause of pressure or friction over an area.
Corns develop in direct response to abnormal pressure or friction (rubbing) over an area of skin on the feet. This pressure or friction may be linked to or exacerbated by:
Once a corn is present, it doesn’t shrink in size - it only grows with repeated exposure to pressure or friction. As such, you typically cannot get “rid” of a corn at home, but there is a lot you can do to help make life more comfortable at home until you’re able to get it removed by your podiatrist. This includes:
Here at Matt Raden Podiatry, our trusted and experienced podiatrists listen to the concerns, goals and needs of our patients with corns on their feet and utilise evidence-based treatment methods to help you get the best outcomes, including helping to reduce the chance of your corns recurring in the future.
We treat corns simply and effectively by ‘scooping’ out the corn using our medical-grade podiatric instruments. As the skin of the corn is dead skin, this is typically painless, although you may feel some momentary discomfort from the pressure of pushing down on the corn. This is very short-lived and eases immediately once the corn is out. As corns are most often accompanied by surrounding callus, we will also debride this callus back to a comfortable level, meaning you feel fantastic on your feet after your treatment.
Your podiatrist will then discuss strategies to help prevent new corns from arising, based on your unique circumstances and what has likely caused your corns in the first place.
If you’ve developed any type of corn on your feet, whether it’s one corn or many, our team is here to help - and to ensure you have the best experience doing so. We’re proud to go above and beyond for our patients, focusing not only on managing your pain and symptoms, but helping you get the best long-term outcomes in preventing this frustrating problem from continuing to recur.
