According to the neurologist of Zhengzhou Air Defense Hospital, from the initial symptoms of facial paralysis to the cure, it takes about one month to go through four stages of disease development. The first week is facial paralysis; In the second week, the condition was stable; In the third week, facial nerve resuscitation period; The fourth week of facial nerve recovery. Even if the disease is found and treated immediately, it will go through these four different stages of disease development. Especially in the first week, the symptoms will get worse. This is not because the treatment effect is not good, but the normal performance of disease development. Without treatment, the symptoms may be more serious.
