Patient's question:
My son often has redness on the right ear and cheek, but he doesn't have a fever or other discomfort. After consulting, it was said that it might be sympathetic nerve excitement. What is sympathetic nerve excitement? What symptoms can it cause? How is it treated?Doctor's answer:
The sympathetic nervous system has an excitatory effect. When the sympathetic nervous system is excited, the heart rate increases, blood pressure rises, pupils dilate, and it becomes difficult to fall asleep. The sympathetic and parasympathetic nervous systems are a pair of mutually balancing nerves in the human nervous system. When a person is active, tense, or excited, the sympathetic nervous system becomes excited, accelerating heart rate, increasing respiration, and raising blood pressure to adapt to these activities. Subsequently, the parasympathetic nervous system becomes excited, inhibiting excessive sympathetic activity to restore the normal state of the human body.
