The term “entrapment dragon” refers to an acute inflammatory skin disease caused by varicella-zoster virus infection, known in Chinese medicine as waist entrapment fire dragon. The disease occurs mainly in the spring and fall of each year, and the infection is most common in adults. It is believed that the herpes zoster virus does not develop through direct exogenous infection, but rather through reactivation of the latent infection, resulting in the disease. Especially in childhood, varicella-zoster virus infection, which manifests as chickenpox, may be partially latent in the ganglia of the body. Under special circumstances, the immunity of the body is reduced, especially if there are underlying diseases such as immune system diseases, tumor diseases, or the use of special medications, which can easily activate the virus and cause the development of enthesopathy. The disease is mainly characterized by neuralgia, but can also invade the trigeminal nerve and cause pain in other areas. However, it occurs mainly on one side of the body and rarely crosses the midline of the body. Herpes zoster should be given a combination of aggressive antiviral and analgesic treatment, and some patients can still recur after cure.
