Athlete's Foot
A chronic infection caused by various types of fungus, athlete's foot is often spread in places where people go
barefoot, such as public showers or swimming pools. The condition ranges from mild scaling and itching to painful inflammation and blisters. It usually starts between the toes or on the arch and may spread to the bottom and sides of the foot.

Fungal Nails
When a fungal infection progresses,
it may infect one or more nails, turning them yellow, green, black, or other colors. Fungal nail infections can cause nail thickening, inflammation, or sensitivity.

Evaluation
Since fungal problems may be related to other medical problems, your podiatrist needs to look at your medical history, examine your foot and skin, and possibly do other tests.

Medical History
Your podiatrist asks you about any problems you've had in the past, any medications you're taking, the type of
work and activities you do, and the
style of shoes you usually wear.

Exam
During your foot examination, your podiatrist checks for breaks in the
sking, growths, and odor (which can
be a sign of bacteria). Your skin is examined for flaking or scaling, and
your nails are checked for color, thickness, and inflammation.

Tests
Your podiatrist may take a
culture (sample) from the infected
area. The culture may be examined under a microscope or observed in a meduim. These tests can help to determine the cause of your problem
or identify the type of fungus.
