While there is a lot of awareness about the need to wear diabetic or therapeutic footwear, there is little information available on how to differentiate the real from the phony ones. Foot corn can be extremely painful and can obstruct your day-to-day activities.
Unlike edible fungi or mushrooms that live on dead vegetable matter, the fungi and yeast that infect the feet are specialized dermatophytes, meaning that they only feed on keratinized tissue such as hair, skin and nails. Fungal infection in the foot can be confined to the nails and may then spread to the skin, or the other way round, starting on the skin and then infecting the nails. Other names are tinea unguium, dermatophytic onychia, dermatophytosis of the nail, or ringworm of the nail. In the case of dermatophyte fungi and yeast, small invasions are usually dealt with by your body's own natural resistance or defence mechanisms, provided you have a healthy immune system at the time. The first sign of fungal infection in the nails is a slight discolouration of the nail plate. Remember that pressure or friction is the cause of callous.
Sometimes, the pressure of the corn or callus may cause inflammation, which can result in pain, swelling and redness. The body protects skin tissues from pressure or friction damage by producing an area of hard skin. So unless the cause of the pressure or friction is found and removed, calluses and corns will continue to form. Over-the-counter treatments, such as corn plasters, can damage the healthy surrounding skin if you use them incorrectly. Look at and feel each foot for signs of injury including bruises, blisters, broken or cracked skin, hot or cold areas, corns and calluses, and discolouration. If your eyesight is poor, get someone else to check your feet for you. Tinea is a contagious fungal infection of the skin. It usually develops between the toes and along the arch of the foot.
A clavus is a thickening of the skin due to intermittent pressure and frictional forces. The word clavus has many synonyms and innumerable vernacular terms, some of which are listed in the Table below; these terms describe the related activities that have induced clavus formation. The shape of the hands and feet are important in clavus formation. Specifically, the bony prominences of the metacarpophalangeal and metatarsophalangeal joints often are shaped in such a way as to induce overlying skin friction. Toe deformity, including contractures and claw, hammer, and mallet-shaped toes, may contribute to pathogenesis. First, you had better prepare for a basin of warm water to soak the feet every winter night.
Patients with poor vision cutting nails too deep beneath crease line can lead to skin breakage and in patients with poor blood flow to foot can lead to major amputation.Proper nail cutting techniques should be learnt,toe nails should be cut straight,not beneath creaseline. At the center of a corn is often a very dense knot of skin called a core, which is located over the area of greatest friction or pressure. Firm, dry corns that form on the upper surfaces of the toes are called hard corns. Pliable, moist corns that form between the toes are called soft corns.
