Herpes zoster on the head is more serious than herpes zoster on other parts of the body and deserves more attention, as follows: 1. Herpes zoster on the facial trigeminal nerve often involves the ophthalmic, maxillary and mandibular branches of the trigeminal nerve. Involvement of the eye can lead to redness and swelling, conjunctival congestion, and involvement of the cornea can lead to corneal rupture and ulcerative keratitis, which can lead to scarring and even blindness; 2. Ear herpes zoster is often caused by the varicella zoster virus invading the facial and auditory nerves, which manifests itself in herpes in the tympanic membrane of the external ear canal, and can lead to facial paralysis, tinnitus, and deafness; 3. When the geniculate ganglion is involved in the external ear canal When herpes zoster, facial palsy, and ear pain are involved, it is called Ramsey-Hunter syndrome; 4. Another more serious one is herpes zoster encephalitis, which can lead to nausea, vomiting, pain, ataxia, and other cerebellar symptoms. So when herpes zoster appears on the head, it must be taken more seriously.
