Why do blisters form on the bottom of feet?

Update Date: 2024-07-04 Source: Network

There are many reasons for blisters on the soles of the feet. Insect bites can lead to urticarial papules, and athlete's foot caused by fungal infections may also result in blisters on the soles. The cause of herpes zoster should not be overlooked as well. When herpes zoster occurs, the soles of the feet may experience stabbing or burning pain. Additionally, walking for too long or wearing shoes that are too small or tight may also cause blisters.

1. Urticarial papules:

Wind-mass-like blisters can appear on the soles due to allergic reactions caused by insect or mosquito bites. Nedocromil ointment can be applied for treatment.

2. Athlete's foot caused by fungi:

Fungal infections can cause athlete's foot on the soles, leading to blisters on the feet. This condition is relatively common and can be treated with antifungal medications.

3. Herpes zoster:

Herpes zoster occurs on one side of the sole and can cause paroxysmal stabbing or burning pain. It is caused by a decrease in immune function and infection with the varicella-zoster virus.

4. Wear and tear of the soles during walking:

In daily life, due to exercise or hot weather, the feet tend to sweat and develop blisters. Walking for a long time or wearing inappropriate shoes may also lead to blisters on the soles. In such cases, it is important to clean the feet promptly, apply iodine tincture, and prevent infection.
