- Corns and calluses are a build up of thick skin on the foot.
- They are part of the body’s defence system to protect the underlying tissues.
- A foot corn and callus can range from being mildly uncomfortable to painful and debilitating.
- Calluses often appear on the bottom of the foot around the forefoot, as well as the heel and around the sides and tips of the toes.
- Hard Corns can occur on the top and sides of toes and also along the bottom of the foot.
- Soft Corns in most cases appear between the toes.
- People with certain medical conditions, skin types or who undertake certain activities may be more prone to developing corns and calluses.
- Corns and calluses sustained due to heavy weight bearing activities such as running or hiking, if left untreated may further develop into blisters or even ulcers and infection.
- Corns and calluses are a risk factor for people with diabetes or poor sensation and/or circulation as they can potentially contribute to the development of foot ulcers
- Corns and calluses occur when something rubs against the foot repeatedly or causes excess pressure against part of the foot.
- Excessive pressure at the balls of the feet—such as regularly wearing high heels or tight fitting footwear —may cause calluses to develop in this area.
- Shoes that are too big, or the wrong fit for your foot shape can also cause friction and contribute to the development of corns and calluses.
- People with certain foot shapes (excessively flat or high arched) or with deformities of the foot, such as hammertoes, are more prone to corns and calluses.
Signs and Symptoms
- Calluses typically have a rough, dull appearance
- Calluses may be raised or rounded, and they can be hard to differentiate from warts
- Calluses may be painful or cause a sensation of numbness
- Corns are often funnel shaped and dig into the skin rather than protrude out
- Corns can be particularly painful, as they tend to intensify the pressure into one spot
- Corns may develop into ulcers if left untreated
- Corns may feel like a stone or pebble stuck under your foot.
- Corns may be hard or soft depending on the location on the foot.
- Soft corns develop between the toes and in places where skin is pinched between underlying bones.
- Diabetics are at risk if they develop corns or calluses
- Removal of the corn or callus with the use of a specialist instrument
- Biomechanical evaluation
- Footwear advice
- Orthotics to redistribute pressure
- Use of appropriate emollients to keep the skin hydrated and prevent build up
- Advice for ongoing self care and prevention of the reoccurrence of this complaint
- Diabetics and people with poor circulation or neuropathy should have their feet checked and treated regularly.
