What causes red spots on the feet?

Red spots on the feet may be caused by physiological factors, but conditions such as eczema or urticaria cannot be ruled out. Specific causes are analyzed as follows:

I. Physiological Factors

If shoes are not breathable, or if there is excessive sweating or overexertion of the feet, skin damage may occur. No treatment is necessary; simply switching to breathable shoes and socks is sufficient.

II. Pathological Factors

1. Eczema

Skin damage may develop after prolonged exposure to damp, cold environments or bacterial infection, often accompanied by itching of the feet.

3. Urticaria

When exposed to allergens or insect bites, skin epidermal cells can be stimulated, leading to urticaria, which may also cause local redness, swelling, and itching.

It is also possible that red spots are caused by other factors such as hemangioma. It is recommended to visit a dermatology department at a local hospital for accurate diagnosis. After identifying the underlying cause, follow medical advice to apply topical medications such as tacrolimus ointment, or take oral antihistamines like loratadine tablets or cetirizine hydrochloride tablets to manage the condition. Additionally, maintain proper hygiene of the affected skin area and avoid scratching.
