Corns like calluses develop from an accumulation of dead skin cells on the foot, forming thick, hardened areas. They contain a cone-shaped core with a point that can press on a nerve below, causing pain. Corns are a very common ailment that usually form on the tops, sides and tips of the toes. Corns can become inflamed due to constant friction and pressure from footwear. Corns that form between the toes are sometimes referred to as soft corns.

Some of the common causes of corn development are tight fitting footwear, high heeled footwear, tight fitting stockings and socks, deformed toes, or the foot sliding forward in a shoe that fits too loosely. Soft corns result from bony prominences and are located between the toes. They become soft due to perspiration in the forefoot area.
Complications that can arise from corns include bursitis and the development of an ulcer.

Treatment and Prevention
There are very simple ways to prevent and treat the corns. You should wear properly fitted footwear with extra room in the toe box (toe area). Avoid shoes that are too tight or too loose. Use an orthotic or shoe insert made with materials that will absorb shock and shear forces. Also avoid tight socks and stockings to provide a healthier environment for the foot.
Try to steer away from corn removing solutions and medicated pads. These solutions can sometimes increase irritation and discomfort. Diabetics and all other individuals with poor circulation should never use any chemical agents to remove corns.
If the problem persists, consult your foot doctor.

A foot corn is an area of thickened skin that occurs in areas of pressure. In the foot, the skin will thicken up to protect itself when the areas of high pressure have not been eliminated. Eventually, you will experience a great deal of pain in the foot at the area of the corn.
Foot corns appear as a thickening on the top of your toes. Hard corns are normally located on the outer surface of the little toe or can also be found on the surface of other toes. Foot corns can often appear in between the toes. The first step in foot corn treatment is to eliminate the source of pressure. Sounds simple enough… right? First you should avoid wearing tight fitting shoes as this will allow your feet to breath as well as reducing the pressure on your foot; pressure that can over time cause a foot corn to develop.
Tight fitting shoes can rub against your feet causing extreme pressure and pain… and remember reducing pressure on certain areas of the foot is one of the easiest ways to avoid a foot corn.
Beginning foot corn treatment options would consist of placing a moleskin pad over the foot corn to relieve pressure around the foot corn.
Remember, corn paint, cure or plasters will only treat the symptom and not get to the root cause of the problem.

You have to relieve the cause of the pressure.
Soaking your foot corn with warm water and Epsom salt for at least five minutes, three times a day will help to soften the corn.
Another common foot corn treatment is using a pumice stone on the corn which will file it down and it will begin to remove part or all of the corn.
