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.
If you have diabetes or another condition that causes poor circulation to your feet, you're at greater risk of complications. Corns are smaller than calluses and have a hard center surrounded by
inflamed skin. Corns usually develop on parts of your feet that don't bear weight, such as the tops and sides of your toes. Corns can be painful when pushed or may cause a dull ache. Calluses usually
develop on the soles of the feet, especially under the heels or balls, on the palms, or on the knees. Calluses are rarely painful and vary in size and shape. They can be more than an inch in
diameter, making them larger than corns. When shoes are too tight or have very high heels, they compress areas of your foot. Repeat two to three times; switch feet.
Metatarsal pads, soft insole inserts, and modifying standing areas with a soft surface (e.g., a rubber floor mat) may relieve the discomfort of tender calluses. Custom-moldedarch supports (called
orthotics ) or over-the-counter arch supports may help if flatfeet contribute to the problem. If one of the metatarsals is too low, an orthotic cutout can equalize pressure on the ball of the foot.
Because the thickness of the callus causes pressure, reducing the overgrown tissue by soaking the feet in warm water and filing down the callus with a pumice stone to smooth down the thick tissue may
be helpful. In severe cases, podiatrists may use a device called a sterile surgical blade to remove the outer layers of thickened skin. In some cases, one of the metatarsals may be too low or too
poorly positioned for orthotics to work.
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.
