There are some pimples on my neck that itch when I sweat. What is this?

In summer, the temperature is high, the humidity is high, and the body sweats a lot, so it is not easy to evaporate. Sweat infiltrates the cuticle of epidermis, leading to the occlusion of sweat gland ducts, which is easy to produce miliaria.

Take a bath frequently, do not use too hot water, keep your skin clean and dry, and apply prickly heat powder.

In severe cases, you can also take traditional Chinese medicines or preparations that clear away heat, promote diuresis and relieve summer heat.
