Having shingles, especially facial shingles, can leave sequelae if not treated promptly. If it occurs in the head, it often tends to cause migraines, mainly causing a headache on one side rather than the whole headache. If it occurs in the eye, it tends to cause corneal ulcers and eventually can even cause blindness. If it occurs in the facial nerve, injury to the facial nerve can cause facial paralysis, resulting in facial asymmetry and sometimes drooling. If it hurts the auditory nerve, it can cause deafness, tinnitus, and symptoms such as vertigo, nausea, and vomiting. In addition, facial herpes zoster can cause loss of taste, especially in the first 1/3 of the tongue, so facial herpes zoster is usually serious and can leave a variety of sequelae.
