My daughter is fifteen months old. It was hot, and a lot of little red beans grew on my back last night. As shown in the picture, it should be a little itchy. What is this? It's prickly heat

The picture is not very clear. If there is sweat, it is necessary to consider prickly heat. Miliaria, also known as miliaria, is a superficial inflammatory skin disease that is common in summer or hot environment. Most of the sweat is not easy to evaporate in the hot and muggy environment, which makes the cuticle wet and swollen, which leads to the narrowing or blockage of the sweat tube and the sweat stays in the sweat tube. Pressure rise, sweat tube rupture, sweat extravasation and disease. According to the different parts of injury and sweating, it can be divided into white miliaria, red miliaria, pus miliaria and deep miliaria. Topical drugs such as mint calamine lotion and pine pollen abscess need to be treated with erythromycin ointment and other anti-infection ointments. Itching is obvious, and antihistamines such as loratadine and mizolastine can be taken orally. Severe suppurative infection requires oral antibiotics.
