Pus-filled blisters on the soles of the feet

Blisters with pus on the soles may be caused by conditions such as dyshidrotic eczema, athlete's foot (tinea pedis), or palmoplantar pustulosis, and treatment should be targeted according to the specific cause. Detailed analysis is as follows:

1. Dyshidrotic Eczema

Dyshidrotic eczema commonly occurs in summer. When this condition develops on the feet, it may lead to symptoms such as itching and blistering around the feet. Once blisters break, they are prone to bacterial infection and can become pus-filled. Under medical guidance, topical medications such as mometasone furoate cream or calamine lotion may be used for symptom relief.

2. Athlete’s Foot (Tinea Pedis)

This condition is a fungal skin infection. When fungi invade the skin of the soles, they can cause local blisters and itching. Following bacterial infection, the affected area may discharge pus. As directed by a physician, topical antifungal agents such as compound clotrimazole cream or ketoconazole cream can be applied to alleviate symptoms.

3. Palmoplantar Pustulosis

In this condition, small pustules develop on red patches of skin, typically on the palms and soles. These pustules gradually rupture, crust over, and peel off, while new pustules continue to form beneath the scales and may persist for prolonged periods without healing. Under medical supervision, topical treatments such as triamcinolone acetonide/econazole cream or betamethasone cream may help relieve symptoms.

In addition to the above common causes, other possible conditions include eczema, impetigo, and pemphigus. If any discomfort or symptoms occur, prompt medical evaluation and timely treatment are recommended to avoid disease progression.
