Patient's question:
My 8-year-old son often gets headaches when he's tired or hot. What's wrong? This has happened to him many times, but he hasn't had a thorough check-up yet.Past treatment history and effectiveness: None.
What kind of help is needed: Is it serious? Should he go to the hospital?
Doctor's answer:
There are many reasons for headaches, such as colds with fever, problems with the five senses, abnormal blood pressure, obstacles in the head, anemia, constipation, gas poisoning, alcohol poisoning, and nervous fatigue, all of which can cause headaches. Headaches from exhaustion or heat may be due to the meninges being hit, or the blood vessels contracting, increasing tension, or it may be a signal from the brain indicating insufficient oxygen, requiring more oxygen. As long as blood rich in oxygen flows to the painful area, the headache will disappear immediately.
