Corns and calluses are areas of hard, thickened skin that develop when the skin is exposed to excessive pressure or friction. They commonly occur on the feet and can cause pain and discomfort when you walk.

Corns

Corns are small circles of thick skin that usually develop on the tops and sides of toes or on the sole of the foot. However, they can occur anywhere.

Corns are often caused by wearing shoes that fit poorly or certain designs that place excessive pressure on an area of the foot.

Corns often occur on bony feet as there's a lack of natural cushioning. They can also develop as a symptom of another foot problem, such as:

  • bunion – where the joint of the big toe sticks outwards as the big toe begins to point towards the other toes on the same foot
  • hammer toe – where the toe is bent at the middle joint

Calluses

Calluses are hard, rough areas of skin that are often yellowish in colour. They can develop on your foot, most often around the heel area or on the skin under the ball of the foot.

They can also develop on the palms of the hands and knuckles.

Calluses are larger than corns and do not have such a well-defined edge. As callused skin is thick, it is often less sensitive to touch than the surrounding skin.

Calluses develop when the skin rubs against something, such as a bone, a shoe or the ground. They often form over the ball of your foot because this area takes most of your weight when you walk. This is particularly the case when high heels are worn regularly.

Excessive pressure on bony areas of the foot, badly fitting shoes, dry skin and reduced fatty padding are all possible causes of calluses.

Treating corns and calluses

If you have a corn on your foot, you should see a podiatrist, also known as a chiropodist, who can advise you about treatment. In most areas of the UK your GP will be able to refer you on the NHS.

Find foot care specialists in your local area.

Corns on feet will not get better unless the cause of the pressure is removed. If the cause is not removed, the skin could become thicker and more painful over time.

A corn is a symptom of an underlying problem. You should only treat it yourself when you know what has caused it and after you have spoken to a specialist about the best way to manage it.

Over-the-counter treatments for corns, such as corn plasters, are available from pharmacists. However, they do not treat the cause of the corn and may affect the normal, thinner skin surrounding the corn.

Corn plasters may not be suitable for certain people, such as those with diabetes, circulation problems or fragile skin.

As with corns, you should only treat calluses yourself after a podiatrist has identified the cause and advised you about treatment.

The podiatrist may be able to treat corns or badly callused areas using a sharp blade to remove the thickened area of skin. This is painless and should help reduce pain and discomfort. They can also provide advice on self-care and prescribe special insoles.

You can also help prevent corns and calluses by looking after your feet and choosing the right shoes to wear.

Hi.
I have two painful corns, one on each foot (3rd toe), both of these toes are hammer toes.
I struggle to find shoes to fit properly due to the pressure and pain i get.
My shoe size is a 5 1/2 but have to buy a size 6.
I have tried corm removal several times which works for a little while then they re appear.
I was wondering if it was worth me consulting my gp for a referral for my toes to be straightened?
or can you advice anything else?

My educated guess would be you are still getting too much pressure on your toe. This will be probably either due to the way you lift the foot from the floor (using the muscle that should be for moving your big toe up and not he muscle that actually rotates your foot on the ankle) or the footwear is not suitable for you. Perhaps you could try a different podiatrist, one who will instruct you more on your feet and their functon and the demands your shoes and body place on them. 9 times out of 10 it is shoes that are to blame

I have a corn under my toenail - how do I get rid of this? I saw a chiropodist who said he had got rid of it, I changed my shoes to leather upper shoes as he suggested, and it was fine for a while, but now it has come back and its so painful!!
