The neck will turn red when the weather is hot. What is the reason?

Rubella is a maculopapular rash higher than the skin, which often accumulates into pieces and merges into pieces. Because this disease often occurs suddenly or quickly, leaving no trace, it is commonly known as "wind pimple".

This disease is called "hidden rash" in Su Wen Si Shi Ci Lun. "Etiology" is divided into "white rash and red rash" and puts forward the name of "adding three fields to the upper disease"; It was not until the Tang Dynasty that "Thousand Daughters to Prescription" was named "Rubella". In the Song Dynasty, the theory of three causes and one disease syndrome further divided the occult rash into "white ones are women's membranes, and red ones are blood wind".

If the rash is as bright red as smear Dan, it is called Danbu, which is discussed in another article.
