Prickly heat and prickly heat boils mostly occur in infants under the age of one, often on the head, back and armpits, and are a common skin disease in summer. The cause is high temperature and high humidity in summer, so the body sweats a lot and the sweat cannot evaporate in time, so the sweat gland holes in the epidermis are blocked, forming small papules or papules called prickly rash, which is painful or itchy. If the skin is scratched, it can become infected and expand to form prickly heat boils. If prickly heat occurs, you should avoid scratching and should not wash with hot water or scrub with soap. After bathing with warm water, put on cool prickly heat powder, or use camphor and sulfur, or glyburide lotion to apply externally several times a day, but do not use oily ointment or paste to prevent evaporation of sweat. If there is no obvious secondary infection, it is not necessary to take internal antibacterial agents, but to take some appropriate amount of heat and dampness clearing Chinese medicine, such as: honeysuckle or mung bean soup. Generally, prickly heat will subside soon with proper treatment. If the prickly heat infection forms an abscess, it should be treated by a doctor in a timely manner. Children with obvious local infection or fever should be given antibacterial agents, and multiple prickly heat boils often have different pathological changes at the same time and should be treated in multiple ways. Prevention is especially important in the summer season. In addition to keeping the room ventilated and avoiding high room temperature. Children should be dressed loosely. Bathe regularly, cut hair and nails in a timely manner. Wash and iron clothes in boiling water and dry them in the sun during the illness. Keep the skin clean and dry, especially for infants and children, and change diapers and turn over regularly. Take precautions so that prickly heat boils don’t get stuck.
