What is sweat herpes

Dyshidrosis is a special type of eczema that occurs more frequently in summer. Common symptoms include small blisters on the palms that are slightly above the skin surface, with varying degrees of itching and burning sensations, which usually occur regularly every year.

Causes of sweat herpes

The cause of the disease is still unclear, but it may be related to multiple factors.

Genetic factors: Relevant studies have shown that dyshidrotic eczema may be inherited as an autosomal dominant trait and may occur in families.

Local contact irritation: Alloy products containing metallic nickel and chromium, the compound potassium dichromate and some spices may also cause sweat herpes.

Physical factors: People with allergies or hyperhidrosis are prone to dyshidrosis, especially those with hyperhidrosis, where the incidence rate is 2.5 times that of normal people.

Psychological factors: Mental stress, staying up late, fatigue, etc. can also easily induce dyshidrosis.

Can blisters be popped?

It is not recommended to puncture the blisters. Generally, the blisters will be gradually absorbed by the human body. If they are punctured, inadequate disinfection may cause fungal infection.

What is the difference between dyshidrotic eczema and tinea pedis?

Tinea pedis is caused by fungal infection, usually occurs on one hand or foot, asymmetrically, and is contagious. Dyshidrotic eczema is usually symmetrically distributed on both hands and feet, is not contagious, and is common on the sides of the fingers. In severe cases, it will grow on the palms and soles of the feet. Dermatologists will take the patient's dandruff for fungal examination. If the result shows that the fungus is positive, it can generally be diagnosed as tinea pedis.

Treatment of sweat herpes

1. Systemic treatment (oral medication). Usually used for patients with severe itching. Prednisone acetate 20-30 mg/day, for 5-7 days; can also be combined with antihistamines such as loratadine, cetirizine, etc. If the effect is still unsatisfactory, immunosuppressants such as methotrexate and azathioprine may be needed.

2. Topical medications. During the blister stage, calamine lotion can be applied externally; after desquamation occurs, glucocorticoid ointments (such as triamcinolone acetonide urea ointment, etc.) can be applied externally; for those with repeated local desquamation, dryness and pain, 2%-5% salicylic acid ointment, 10% urea fat, etc. can be applied externally.
