What is hard skin?
Hard skin (also known as callous) is the thickening of the skin. This is the skins way of protecting itself, so the skin doesn’t break.
It commonly occurs over the joints of your toes, the heels and the balls of your feet.
If the skin dries, it may crack or split and may become infected.
If left untreated the build-up of hard skin can be painful and regular self-care can prevent this.

What is a corn?
Corns are caused by pressure and friction over bony areas. A corn is a plug of tough skin, often under hard skin and can be quite painful.
There are several different types of corns:
Hard corn |
This is the most common type and is caused by pressure. Normally they have a build-up of hard skin over them. |
Soft corn |
These corns appear in between toes where the skin is moist from sweat or not drying your toes properly. They look white and feel rubbery to touch. |
Seed corn |
This type of corn are very small and usually painless, normally caused by dry skin. |
Vascular/ Neurovascular corn |
These are corns that can have a blood vessel or nerve attached to them. They can be very painful and tender to touch. |
Fibrous corns |
Can be painful and occur if not treated or prevented for a long time. |
Common causes of hard skin and corns
- Ill-fitting footwear causing pressure or rubbing over the skin
- Foot shape/structure
- Dry skin
- Health conditions and medications causing dry skin
- Genetics
- Smoking
- Obesity
Examples of hard corns, soft corns and seed corns



What is the difference between a corn and a verruca?
- Verruca appear to have small black dots (like a pepper pot) present in the skin
- The lines of the skin are moved around the verruca
- They can appear anywhere on the skin
- Pain may be felt when squeezed from the side
- Corns form over a pressure area on the foot. This most commonly happens over a bony joint
- The lines of the skin are not disturbed and lie over the corn
- The overlying build of up of skin may have a yellow appearance
- Pain will be felt on direct pressure

How to self-treat hard skin and corns
Do |
Don’t |
When skin is dry use a pumice stone or file over the area of hard skin. | Use corn plasters or paste that contains acids. |
Wear well-fitting shoes with a wide toe box and Velcro/tie laces. | Pick at corns or callous. |
Wear socks with your shoes. | Apply any moisturising cream between the toes. |
Dry your feet well after washing taking care in between the toes. | Wear high heels, uncomfortable shoes or shoes that are wrong size. |
If in between the toes is moist use surgical spirit, apply with a cotton bud to dry area up. Never use on broken skin. | If your feet are at risk (you have diabetes or circulation problems) don’t use battery operated callous removers. |
You can purchase wedges and toe covers to prevent toes from rubbing – always remove at night. | Â |
When and how to refer into NHS Podiatry
A regular self-care routine should keep foot problems to a minimum.
If your foot care issues are not improving with regular self-care treatment and are becoming painful/ uncomfortable you should seek help from a private Health and Care Professions Council (HCPC) registered podiatrist.
A referral to NHS podiatry should be made if you have:
- Painful corn that reduces your ability to walk
- Have any breaks in the skin
- Infection (redness, pain any discharge etc.)
How can I, my family or carers help manage my hard skin and corns?
Follow the advice on how to self-treat hard skin and corns described on this page. A printable version is available below.
Visit our personal foot care page for more self-care information.

This is based on some of these areas of your lifestyle that go relatively unnoticed, in your life, until one day this comes sharply in to view then it stings you, resulting in your foot pain and now you pay attention, seeking help.
Weight reduction
People who tend to have increased weight can have more prolonged pain and poorer tissue healing due to increased levels of inflammation in the body. Reducing your weight can generally help improve and pain and the healing process.
Shoes
Shoes that have flexible soles generally offer the foot less support and can increase the stress in soft tissues in your feet. If you have shoelaces make sure they are tied appropriately. Avoid wearing hard, flat or unsupportive shoes.
Activity modification
Pacing is the term used for breaking down an activity or task. This can be done by taking regular breaks and prioritising daily activities can help. This can also help prevent ‘over-stimulating’ the pain system, so it is important to plan rests and set achievable goals.
Partnership
Your partnership with our MSK podiatrists, is based on the aims from NHS Scotland’s Realistic Medicine strategy, for you using healthcare services to feel empowered to discuss your treatment fully with our clinicians, including the possibility a suggested treatment might come with side effects – or even negative outcomes.
Additional information
Acute Injury Management
POLICE is an acronym (Protection, Optimal Loading, Ice, Compression and Elevation) that is used as a management strategy for many injuries and conditions for the first 24 to 72 hours.
- Protection and relative rest are advised immediately after injury for the first 24 to 72 hours.
- Optimal Loading refers to having a balanced rehabilitation program which encourages early and gradual activity to improve recovery. How you progress will vary from person to person depending on the injury. It is about finding the injured areas happy place and increasing slowly and gradually.
- Ice may be used for reducing pain and swelling. There are safety points to follow when you use ice:
- Don't ice over a numb area or open wound. If the skin is numb you won't notice if you're developing an ice burn and ice on an open wound can increase the risk of infection.
- Be wary of ice burns – don't apply ice directly to the skin, wrap an ice pack in a clean, damp tea towel before applying. Avoid prolonged exposure to ice, 10-20 minutes is usually adequate.
- Apply crushed ice/frozen peas wrapped in a damp towel for 10-20 minutes, 2-3 times per day for the first 5-7 days post injury/ flare up of pain.
- Stop applying ice if there are any negative effects such as increase in pain or swelling or skin soreness.
- Compression and Elevation are helpful for reducing inflammation. This can be done by keeping your joint raised on a pillow and compressed by wrapping a bandage around it.
Do not make the bandage too tight and do not wear tubi-grip or any compression bandage in bed at night. - Heat: After 2-3Â days, you may find that heat is more relaxing.
You could use a heat pad or a hot water bottle with an insulated cover on it. Make sure this is not too hot and is not directly touching your skin.
You should do this for 10 to 15 minutes, 3 to 4 times a day.
What do I do if my symptoms flare up?
Flare ups of pain are common. Some people have recurrent flare ups of pain so it is important to know how best to manage these flare ups. In most cases a pain flare-up will settle within 6 weeks.
Top Tips
- You will likely find it helpful to rest a bit more but it is still important to keep active. This will help to avoid becoming stiff and your muscles becoming weak.
- If you aim to get a balance between rest and activity it should help your pain to settle down. You may be sore at first, however, start slowly and gradually increase the amount you do.
- Reduce movements or tasks that aggravate your symptoms. This can help especially in the early days.
- Adopting positions or movements that reduce your pain can be useful.
Pain Relief
Analgesia
- Analgesia also known as pain relief can be an important part in helping you manage your symptoms and allow you to stay active.
- Taking suitable pain relief regularly allows you to move more normally and continue your usual activities without causing any damage. It is unlikely that medication alone will resolve your pain totally. For this reason we are using the term pain relief (A 30-50% reduction in pain would be deemed to be a good success).
Paracetamol
- Paracetamol is a good general pain management medication. It is used to help manage lots of different types of pain.
- Sometimes people believe they need something ‘stronger’ than paracetamol when in fact, taking a regular dose rather than a one-off dose is more effective.
- Spreading the doses of the paracetamol evenly out over a day will help you control your pain. Visit NHS Inform for more detailed information on paracetamol.
Non-Steroidal Anti-Inflammatory Drugs (NSAIDS)
- NSAIDs are medications that can reduce swelling around joints and nerve endings to give pain relief. They are particularly useful
in treating inflammatory type pain. Two commonly prescribed NSAIDs are ibuprofen and naproxen. - Although NSAIDs can be very useful they are not suitable for everyone. Visit NHS inform for further information related to NSAIDs.
There are other forms of pain relievers available. If you feel your current pain relievers are not helping your pain or you are
experiencing any side effects from your medication, please seek advice from your GP or pharmacist.
For general information on medication visit NHS Inform.
Staying in work and returning to work
We know that staying in work or returning to work as soon as possible is good for your mental and physical health.
If you have problems with activities at work, it may be helpful to ask for a workstation/workplace assessment or talk with your manager or Occupational Health Department. This can help with alterations or provision of equipment or altering your working day or tasks.
There are organisations which can support you at work or help you return to work. You can visit Knowledge Scotland for further information.
Weight Management
Weight Reduction – People who are overweight tend to have more prolonged pain and poorer tissue healing due to increased levels of inflammation in the body. Reducing your weight can generally help improve the healing process.
A good indicator of whether you need to lose weight is your body mass index (BMI), which you can calculate with the NHS BMI calculator.
If your BMI states you are overweight or obese it is likely that losing weight will reduce your symptoms. Carrying extra fat also increases your risk of heart disease, stroke, type 2 diabetes, and some cancers. Reducing your portion sizes and eating a balanced diet can be helpful in reducing weight. NHS informs provides a free online 12-week weight management programme to get you started right away.
If you need a little more help and feel that you would benefit from working with others in group sessions NHS Lanarkshire’s Weigh to Go programme, groups in North and South Lanarkshire, will help you become more active, eat well and lead a healthier lifestyle.
Smoking
Smoking can affect how your body recovers from musculoskeletal problems. If you smoke then the good news is that by stopping smoking it can improve your health in many different ways. Giving up smoking is not something you have to do on your own. You’re twice as likely to stop smoking successfully if you get the right support from the NHS. There is a free NHS stop smoking service available in Lanarkshire to help you succeed.
Chronic Pain
Some people will have pain which persists beyond the expected time frame for their condition. For further information on this and how best to manage it please visit our Chronic Pain webpage.
Pain Association Scotland is a national charity that delivers professionally led self-management pain education in the community.
