Question
The patient previously suffered from poliomyelitis and has recovered, but recently experienced numbness on one side of the face due to a severe cold, making it difficult to close the mouth.
Answer
Poliomyelitis is a common and frequently occurring disease, usually caused by wind-cold, leading to facial muscle paralysis. It is recommended that the patient visit a specialized hospital for facial nerve diseases to receive treatment, which can help alleviate the condition. Early diagnosis and treatment not only save medical costs but also avoid interference and therapeutic effects from inappropriate medication use.
