Question
During the recovery period from facial paralysis, the left side of the face sometimes twitches involuntarily. What could be the cause?
Answer
This symptom may be a manifestation of Bell’s palsy or facial neuritis, possibly related to viral infections or catching a cold. The onset is usually rapid, with Bell’s palsy reaching its peak within a few hours to a few days. Some patients may experience persistent pain and tenderness behind the affected ear and over the mastoid process 1-2 days before the paralysis. Treatment principles include improving regional blood circulation, reducing facial nerve edema, alleviating nerve compression, and promoting neural function recovery. Antiviral treatment, nerve nutrition, hormone use, and supportive symptomatic therapy are required during the acute phase. Consider complementary therapies such as acupuncture or physical therapy.
