Every summer, many people grow small, clear blisters between their fingers. Some people think it is eczema, but it is actually caused by sweating herpes, a type of skin eczema named sweating herpes, which is related to sweating. The manifestation of herpes sweat is mainly deep in small blisters, which may be related to viral infection and is not significantly contagious. When the herpes appears, the application of compounded stove glycolic lotion has an antipruritic effect. When the herpes falls off and the skin appears locally peeling and dry, treatment with urea cream, anti-inflammatory cream, etc. is available. If the symptoms are more severe, corticosteroid creams are available and can usually be controlled in 3-5 days. The main protection against sweating is to avoid sweating, to keep hands away from water and detergents, and to replace toiletries with less irritating baby products.
