Patient's question:
My husband suddenly had facial stiffness a few weeks ago and said he couldn't talk, which scared us. We took him to the hospital for a thorough examination, and the doctor said it was facial paralysis. I want to know what causes facial paralysis and what kind of help is needed: What are the causes of facial paralysis?Doctor's answer:
The causes of facial paralysis:1. The blood vessels that supply nutrients to the facial nerves are affected by cold wind or cold, leading to severe pain and causing cerebral edema, swelling, compression, and blood stasis in the nerve tissue.
2. Most patients experience cold wind or cold water exposure on the affected side of the head before the onset of the condition, such as from using a fan or encountering cold water.
3. A smaller portion of patients show signs of viral infection before or after the onset of the condition, commonly experiencing symptoms like colds or ear infections.
