Athlete’s foot is a fungal infection caused by the fungus, Tinea pedis. Warm, moist conditions give the fungus the best chance for growth. Athletes' foot generally looks like itchy, flaky skin in the web spaces between the toes but can occur around the soles of the feet. As the fungus grows these flakes become white and begin to peel off. Skin under the scales is red and may be itchy or sore.
If left alone, the skin between the toes can become badly broken and painful, inflamed and sore. Broken skin can lead to bacterial infection, which is a more serious condition (this would appear weeping with pus or yellow crusts). The web space between the 4th and 5th toes is the most commonly affected. The condition may spread to the sole of the foot and even to the upper surface. It looks different to eczema and dermatitis in that these do not affect the web spaces between the toes.
A bunion is a lateral displacement of the big toe joint. It results in an increase in the prominence at the base of the toe and inturning of the toe itself, with bunching and compression of the other toes. Tight shoes and high heels aggravate this.
Corns are hardened areas of skin produced in response to trauma. They occur when skin over bony prominences is irritated, for example by ill fitting shoes.
Verracae are viral infections caused by the same virus as a wart. They usually affect pressure bearing areas of the foot, the lesion is pressed into the skin, giving rise to a hard plaque of dry skin, with a small central ulcer revealing several black roots.
