Corns and calluses
Corns and calluses are thickened layers of skin caused by repeated pressure or friction.
Causes, incidence, and risk factors
Corns and calluses are caused by pressure or friction on skin. A corn is thickened skin on the top or side of a toe, usually from shoes that do not fit properly. A callus is thickened skin on your hands or the soles of your feet.
The thickening of the skin is a protective reaction. For example, farmers and rowers get callused hands that prevent them from getting painful blisters. People with bunions often develop a callus over the bunion because it rubs against the shoe.
Neither corns nor calluses are serious conditions.
Symptoms
- Skin is thick and hardened.
- Skin may be flaky and dry.
- Hardened, thick skin areas are found on hands, feet, or other areas that may be rubbed or pressed.
Signs and tests
Your health care provider will make the diagnosis after observing the skin. In most cases tests are not necessary.
Treatment
Usually, preventing friction is the only treatment needed. If a corn is the result of a poor-fitting shoe, changing to shoes that fit properly will usually eliminate the corn within a couple of weeks. Until then, protect the skin with donut-shaped corn pads, available in pharmacies. If desired, use a pumice stone to gently wear down the corn.
Calluses on the hands can be treated by wearing gloves during activities that cause friction, such as gardening and weight lifting.
If an infection or ulcer occurs in an area of a callus or corn, unhealthy tissue may need to be removed by a health care provider and treatment with antibiotics may be necessary.
Calluses often reflect undue pressure placed on the skin because of an underlying problem such as bunions. Proper treatment of any underlying condition should prevent the calluses from returning.
Expectations (prognosis)
Corns and calluses are rarely serious. If treated properly, they should improve without causing long-term problems.
Complications
Complications of corns and calluses are rare. People with diabetes
INGROWN TOENAILS
An ingrown toenail, also known as onychocryptosis or unguis incarnates, is a painful condition of the toe. It occurs when a sharp corner of the toenail digs into the skin at the end of or side of the toe. Pain and inflammation at the spot where the nail curls into the skin occurs first. Later, the inflamed area can begin to grow extra tissue or drain yellowish fluid.
- If left untreated, an ingrown toenail can progress to an infection or even an
- abscess that requires surgical treatment. Osteomyelitis is a rare complication of an infected toe, in which the bone itself becomes infected.
- Ingrown toenails are common in adults but uncommon in children and infants. They are more common in men than in women. Young adults in their 20s or 30s are most at risk.
- Any toenail can become ingrown, but the condition is usually found in the big toe.
BUNIONS & TOE DEFORMITIES
Bunions are a common problem that most people experience as a bony protuberance at the base of the big toe. A bunion, however, is more complicated than simply a bump on the foot.
When a patient has a bunion, the big toe angles in toward the other toes, a condition called hallux valgus. Bunions are most common in women, and the cause is most often unsuitable footwear.
A bunion is a prominence on the inner side of the foot at the base of the big toe. The bunion usually forms because of the alignment of the bones of the forefoot. This causes pressure and prominence of the base of the big toe. Irritation of the soft tissues surrounding this part of the foot causes further swelling and pain.

Questions - Answered:
Shoes that don't fit properly are the source of many foot problems - the higher the heel, the worse the problems tend to be. Slip-on shoes are one of the worst culprits, as they cause the foot to slide forward and cramp the toes. Worst of all are court shoes, as they are low-fronted, giving no support to the foot, and tend to be too narrow in the toe box. If you have foot problems, it is important to look at the cause, which is most likely to be your shoes. For frequent, everyday wear, choose a low-heeled shoe - no higher than 4cm - which has a rounded toe. Find out more in our shoe section.

A verruca is a viral infection and can be picked up from coming into contact with the virus. To try and avoid catching one try not to come into contact with the changing room floor by wearing something like flip flops in the changing room and to the pool edge. If you already have a verruca, keep it covered. Verruca socks are available, which are slim fit rubber socks that prevent the virus being spread or picked up. (Not very popular due to the look of them). Take a look at our page on verrucas to find out how to prevent or treat them.

A lot of people think that a corn has a root, and that you need to remove the root in order to get rid of the corn. This is not the case. A corn is simply made up of hard skin that occurs over a bony prominence such as a joint. It is usually the result of pressure or friction to the area. The central area of the corn that appears to go deeper into the toe, isn't something growing from inside, but is where the area of pressure (usually from the shoe if it is on the toe) is greatest. The skin thickens as a result of too much pressure/trauma and makes it look like there is a core or root that needs removing. Look at our page on corns and callus to find out how best to prevent them.

The usual test is to pinch the suspect area. Verrucae are usually more painful than corns when pinched. Corns and callous are more likely to affect weightbearing areas, whereas verrucae can appear on any area.

If your feet hurt something is wrong! More often than not the shoes are a poor fit or style.

The increased weight could a factor but there are other possibilities. The baby could be pressing on a nerve and the tingling in the feet could be caused by this. Tingling can often be a mild form of neurological disturbance.

There are more sweat glands per inch of our feet than anywhere else in our body - so it's not surprising that many people suffer from sweaty feet, especially in warm weather. For minor problems wash feet morning and evening in warm, soapy water, then dry thoroughly. You can also use an antibacterial wash, which helps deal with foot odour, too. Then apply surgical spirit and dust the feet with talc. Going barefoot whenever you can will help, as will wearing open-toed sandals. For more serious problems there are special foot anti-perspirants. Take a look at our page on Sweaty Feet for more information.

In summer, hard, cracked skin on the heels and balls of the feet are very common, and is often caused by wearing footwear which rubs the skin. Use an emery board or pumice to gently rub away the hard skin, then use a rich moisturising cream, such as an aqueous cream or E45 to soften the skin. Getting into a daily foot care routine will help. For more serious hard skin see a chiropodist/podiatrist for advice and treatment.

"It’s caused by a number of fungal species which you can pick up from anywhere (typically communal areas such as pools, showers and changing rooms) or anywhere where you may walk around barefooted, says registered podiatrist Shuja Qureshi. "The fungus on each bit of skin that falls away from someone else’s feet can be picked up by you if you’re prone."

"A referral to either a podiatric or orthopaedic surgeon is always a treatment option which you could discuss with your chiropodist. Members of the Society will have received as part of their training knowledge of the various surgical procedures, healing times and complications. So you should discuss it with them. It is however important to realise that with all surgery you would have to weigh up very carefully the benefits and risks involved. And sometimes there can be contraindications which would rule out surgery altogether, for example poor circulation."
