Patient's question:
Doctor, I suffered from Bell's palsy (herpes zoster neuralgia) a year ago and went to the hospital for treatment, but it wasn't thorough. My facial expressions are unnatural, and I will never make too many expressions. Even a small smile or squinting feels very tiring. Moreover, I feel a sense of numbness in my head when it's not present. Hello, what is the reason for numbness in the head after Bell's palsy?Doctor's answer:
Herpes zoster virus-induced facial paralysis, incomplete treatment in the acute phase, recurrent head numbness in the later stage suggests postherpetic neuralgia left by facial neuritis. Nerve repair is relatively slow, and symptoms in the postherpetic phase are more difficult to alleviate. If head numbness occurs, oral B vitamins can be taken to nourish the nerves. If the effect is not satisfactory, nerve conduction-blocking drugs can be added. Acupuncture and physiotherapy are generally not very effective.
