Localized burning heat is seen in wind-heat paralysis, a condition in which wind, cold, dampness, heat, and other external evils attack the body and block the meridians, resulting in poor flow of qi and blood. However, some patients start with fever, thirst, red and sore throat, and general discomfort, followed by joint symptoms. At the beginning of the disease, the evil is mainly real. The disease is located in the skin meridians of the limbs. In prolonged illnesses, the disease is mostly due to deficiency of evil, or mixed with deficiency and reality, and the location of the disease is deep in the tendons and bones or internal organs. Clinically, there can be pathological changes such as stasis, blood, phlegm and paralysis, deficiency of qi and blood, re-invasion of evil, and damage to internal organs. It is mainly caused by wind, cold, dampness, and heat that invade the body, resulting in poor flow of qi and blood and obstruction of meridians. Or long-standing phlegm and blood stasis, blocked in the channels, deep into the joints and tendons. Generally, the internal cause is the deficiency of positive energy. Wind, cold, dampness and heat are the external causes. The onset of paralysis is usually not obvious. The pain is wandering or has a fixed location, some are tingling, or numbness, or swelling. Heat urticaria Heat urticaria is a type of dermatological urticaria, mostly occurring in youth, and usually appears after heat (hot drinks, hot baths), emotional excitement and exercise. The symptoms subside when exercise is stopped or after calming down. In severe cases, it may take months or years for the symptoms to subside completely. Erythema multiforme exudativum (EME) is an acute exudative inflammatory skin-mucosal disease, also known as erythema multiforme (EM). Since the disease has the prominent manifestation feature of exudation, it is more accurate to call it erythema multiforme, which is a complete summary of the disease from the name. Millipede burns The millipede is a non-toxic phytophagous insect that does not bite and release toxins, however, when it crawls on the human body and encounters a pounce, the insect body ruptures and the glands on both sides release toxins, which can produce burning, blistering, and hyperpigmentation when a person is infected with its toxins, and can cause severe inflammatory reactions if it happens to enter the eyes. Once the skin comes into contact with this toxin, it must be rinsed immediately with plenty of water.
