Patient's question:
This morning when I left, my mother-in-law was fine, but after I came back, she suddenly couldn't respond and had no facial expression, even a slight smile was very stiff. I'm very afraid she might have Bell's palsy. What are the early symptoms and causes of this condition?Doctor's answer:
Early symptoms of Bell's palsy can cause facial muscle stiffness and symptoms such as crooked mouth corners. Additionally, some patients may experience repeated drooping of the mouth corner. Symptoms may even worsen during slight smiling or when showing teeth, and the affected area cannot frown or close its eyes. The cause of Bell's palsy is likely due to long-term exposure to toxic substances. During treatment, it is important to rest in bed. Avoid strenuous exercise, maintain a calm mood, and do not experience excessive stress.
