what causes a rash on bottom of feet
Athlete's foot, known medically as tinea pedis, is a common fungal infection of the foot. Along with a red or scaly rash, itchiness is a key symptom. Athlete's foot can occur on the soles of the feet as a widespread rash with a powdery appearance, or it can occur as a localized rash between the toes. A more acute type of athlete's foot causes a red, inflamed rash with blisters.
