When the forehead of a 9-year-old child becomes hot, it turns red. What is the reason?

Patient's question:

Sudden onset during hot weather, mainly with red patches on the forehead

Doctor's answer:

Hello, the symptoms caused by eczema are similar to those caused by allergic diseases, so it is important to get a timely diagnosis and treatment. It is recommended to take Chlorpheniramine orally, Vitamin C, and Fengfeng Tongsheng Pill for treatment. Topically, use Compound Ketoconazole Cream. Avoid spicy foods and eat more fresh vegetables and fruits for early recovery.
