Corns and calluses are protective, thickened layers of skin triggered by repetitive friction or pressure. Typically appearing on the feet, toes, or hands, these hardened patches are the body’s way of shielding sensitive tissue. While often harmless, they can become painful or lead to complications if left unaddressed.
What are the symptoms?
The primary signs of these skin conditions include:
- A thick, roughened area of skin
- A hardened, elevated bump
- Tenderness or localized pain beneath the skin
- Skin that appears dry, waxy, or flaky
Why does this disease occur?
These conditions result from repeated friction and pressure. Common causes include:
Improper footwear and hosiery: Tight shoes or high heels squeeze the feet, while loose footwear allows the foot to slide and rub against internal seams. Socks that do not fit correctly can also irritate
Going sockless: Wearing shoes or sandals without socks increases direct skin contact and friction
Manual activities: Repetitive pressure from using hand tools, playing musical instruments, or even writing with a pen can cause calluses on the hands
Genetic factors: Some individuals inherit a predisposition for a specific type of corn that develops on non-weight-bearing areas like the palms or soles
Who is at risk of this disease?
You are more likely to develop corns and calluses if you:
- Wear footwear that increases friction on your feet
- Have physical conditions like hammertoe or bunions (hallux valgus) that create pressure points
- Possess a genetic predisposition for skin thickening on the palms or soles
What are the possible complications?
For most, these are minor issues. However, individuals with diabetes or conditions causing poor blood flow face a high risk of developing infected open sores, known as ulcers, from even minor skin irritation
When should you see a doctor?
Seek medical attention if a corn or callus becomes inflamed or extremely painful. If you have diabetes or poor circulation, consult a professional before attempting any self-treatment, as the risk of infection is significantly higher
How is this disease diagnosed?
A healthcare provider usually diagnoses these through a physical examination. To rule out warts, the doctor may pare away a bit of the hardened skin. If it reveals black points (dried blood) or bleeds, it is a wart rather than a corn
What are the treatment options?
If self-care is not enough, medical options include:
- Trimming away excess skin: A doctor can safely pare down thickened skin using a scalpel
- Using 40% salicylic acid patches to chemically soften the skin
- Custom-made orthotics can help prevent recurrence by correcting underlying foot deformities
- In rare cases, a doctor may recommend surgery to realign a bone causing the friction
How can you take care of yourself at home?
The most effective home care is removing the source of friction. You can use non-prescription salicylic acid in gel or liquid form for larger areas. Before applying medicated patches, gently thin the skin using a pumice stone or nail file.
How can this disease be prevented?
- Buy shoes at the end of the day when feet are swollen. Ensure there is enough room to wiggle your toes
- Apply felt pads or non-medicated bandages over areas that rub against shoes
- Use gloves when using tools, or add protective covers to tool handles
Frequently Asked Questions (FAQs)
Q1. What is the difference between a corn and a callus?
Corns are smaller, deeper, and have a hard center surrounded by inflamed skin. They are often painful when pressed and usually appear on or between toes. Calluses are rarely painful and develop on pressure spots like heels, palms, or knees.
Q2. Will corns and calluses go away on their own?
Yes, in many cases. If you identify and remove the source of the pressure or friction, such as switching to better-fitting shoes, the skin will often return to its normal state over time.
