Tinea Pedis, or “Athlete’s Foot”, is a superficial fungal infection of the feet. It is the most common fungal infection affecting up to 70 percent of the population at some time. Fungal infections are usually enhanced by heat, moisture, and skin break down. Frequently it starts in the moist toe webs, then may spread along the base of the toes and soles of the feet. Not every scaly, red or oozing problem is due to fungal infection. Bacterial infections, dermatitis, psoriasis and other skin diseases can mimic a fungal infection of the foot. Persistent infections should be seen by a care provider.
The rash of tinea pedis commonly has two forms. The moist and inflammatory type is red with areas of blisters, oozing, and scaling. The dry scaly type is slightly red with areas of scaling and thickening of the skin.
Tinea unguim or Onychomycosis is a superficial infection of the nails. It usually occurs in the toenails of persons with tinea pedis. The nail becomes yellow, thick, and even crumbly.
The treatment of tinea pedis involves applying medicated antifungal creams, lotions or powders to the skin, often for four weeks or more. In more persistent or extensive cases, oral antifungal medications may be necessary. In tinea unguim, topical creams or lotions usually do not penetrate the nail effectively. This treatment often requires oral antifungal medications that need close monitoring by a dermatologist or other care provider.
In both tinea pedis and tinea unguim, recurrences after treatment are common. Thus “prevention measures” are an important part of treatment.
– Keep your feet dry!
– After bathing, dry carefully between all toes.
– Use an absorbent or antifungal foot powder.
– Wear “breathable” shoes or sandals when weather permits.
– If your feet sweat easily avoid boots, plastic shoes, sneakers.
– Wear absorbent, cotton socks.
– Change socks at least once a day, more often if they get wet or sweaty.
– Socks and towels should be changed frequently and laundered with hot water. Do not share towels or socks.
Regular cleaning of your shower floor with disinfectant or 10% bleach/water mix is advisable.
