Many patients respond that when they get up in the morning and brush their teeth, they find that their mouths are crooked, they cannot hold water, and they have discomfort such as incomplete closure of the ipsilateral eye, tearing, facial numbness, and pain behind the ear, etc. In many cases, this is facial palsy, and the diagnosis can be confirmed by excluding facial nerve damage caused by other problems such as parotid gland. Brain problems need to be identified. Facial palsy can be treated with acupuncture and needs to be treated early. During the treatment period, you should strictly avoid wind, eat lightly, and ensure sleep time.
