Question
Occasionally, the right upper part of my mouth twitches. What could be the cause?
Answer
Based on the description, it is currently not possible to determine the exact cause, as it may involve various situations. On one hand, it could be due to catching a cold or regional nerve irritation. On the other hand, the involuntary muscle twitching might be caused by fatigue. It is recommended to go to the hospital for a detailed examination, including brain CT or MRI, and there is no need to worry excessively.
