What causes itching at the heel of the foot?
The heel of the foot refers to the posterior part of the foot. Itching in this area may be caused by physiological factors, or by conditions such as athlete's foot (tinea pedis) or eczema. The specific causes are analyzed as follows:
I. Physiological Factors
In dry weather, the body and feet may lack sufficient moisture, leading to localized skin itching. Symptoms usually improve gradually after soaking the feet and applying moisturizer. Wearing ill-fitting shoes can also cause friction between the heel and the shoe, triggering itchiness.
II. Pathological Factors
1. Athlete's Foot (Tinea Pedis)
If the heel becomes infected with fungi, the microorganisms can erode the outer layer of skin, causing localized itching and pain. Athlete’s foot is contagious and can spread through direct contact, so personal protection is important in daily life.
2. Eczema
If the heel is exposed to cold, damp environments or comes into contact with allergens, skin allergy reactions may occur, resulting in significant local pain and itching. Small raised bumps (papules) may also appear on the affected skin.
Itching may also be caused by other conditions such as keratoderma. To determine the exact cause, it is recommended to visit a local hospital for evaluation. Once the underlying cause is identified, targeted treatment should be carried out under a doctor's guidance.
