# Corns and callus: why does hard skin keep coming back?

> What corns and callus are, why pressure matters, and what to expect from a routine foot care appointment in Shepperton.

A tender patch under your foot can make a short walk along the river feel much
longer. Corns and callus are common reasons to arrange routine foot care. The
useful question is not just how to remove the hard skin, but what keeps putting
pressure on that spot.

## Is it a corn or a callus?

A corn is a small area of concentrated hard skin. Callus spreads over a wider
patch. Both can develop in response to rubbing or pressure. Shoes, activity and
the way your foot loads the ground can all matter. A picture online cannot
reliably identify every lump or painful patch.

The [NHS overview of corns and calluses](https://www.nhs.uk/conditions/corns-and-calluses/)
explains the usual features and when to seek help. A verruca is a different
condition, so guessing and applying a product for the wrong problem can waste
time. If the area is changing or you are uncertain, have it examined.

## What happens at a corn or callus appointment?

At our Shepperton clinic, this is part of
[Routine Skin & Nail Care](/treatments/routine-chiropody-shepperton/). Explain
where it hurts, how long it has been there, and whether it troubles you barefoot,
in one pair of shoes or all the time. Let Aaron know what you have already tried.

The area is examined before treatment is agreed. Where appropriate, the thickened
skin is carefully reduced. The conversation also covers what may be pressing or
rubbing on it. That may mean looking at a seam inside a shoe, how much room your
toes have or where the sole has worn down.

You can ask to pause during treatment. If the skin is sore or sensitive, say so;
the aim is an approach that suits your feet, not getting through a predetermined
amount of treatment.

## Why does the hard skin return?

The [Dudley Group NHS guidance](https://www.dgft.nhs.uk/pil/corns-and-calluses/)
explains the role of pressure relief in managing recurrent hard skin.
Removing thick skin does not change the shoes you put back on afterwards. If the
same rubbing or pressure continues, the skin can thicken again. This does not
automatically mean you need a more aggressive removal or more frequent visits.
It means the reason for the pressure deserves another look.

Bring the shoes you actually spend time in, even if they are well worn. Work shoes,
walking shoes and slippers can each tell a different part of the story. It is
also useful to note whether a particular journey, standing shift or activity
sets off the discomfort. These details help make the advice practical.

## What is safe to do at home?

Do not cut a corn or callus yourself. Comfortable, well-fitting shoes that do not
rub are a sensible starting point. Ask a pharmacist about suitable products
rather than assuming that every corn plaster is appropriate for your skin.

If you have diabetes, poor circulation, a weakened immune system or are an older
person, seek professional advice before self-treatment. Get medical advice for
bleeding, discharge, severe pain or symptoms that do not improve. The
[NHS advice](https://www.nhs.uk/conditions/corns-and-calluses/) sets out these
precautions; our [diabetic foot care page](/treatments/diabetic-foot-care-shepperton/)
explains the assessment service at the clinic.

## Do you need regular appointments?

There is no single timetable for every pair of feet. Discuss what keeps you
comfortable and what you can manage between visits. A useful plan should explain
when to return and what changes mean you should get advice sooner.

If nail cutting is difficult too, mention it when arranging the appointment so
both concerns can be considered together. Our
[toenail cutting guide](/advice/help-cutting-toenails/) explains how to prepare.
For anyone unsure which kind of professional to contact, start with
[chiropodist or podiatrist](/advice/chiropodist-or-podiatrist/).

## Quick answers

### What is the difference between a corn and a callus?

A corn is a small, concentrated area of thick skin; a callus is a broader patch. Both can form where the skin experiences pressure or friction. A painful patch should be assessed if you are unsure what it is.

### Will removing a corn stop it coming back?

It can relieve pressure, but hard skin may build up again if the rubbing or loading continues. Footwear advice and pressure relief are part of the plan, alongside treatment where suitable.

### Should I cut off hard skin myself?

No. Do not use blades or scissors on a corn or callus. If you have diabetes, poor circulation, a weakened immune system or are an older person, get professional advice rather than treating it yourself.
