Twitching refers to involuntary muscle contractions that can occur in various parts of the body. These contractions can be brief and may happen in response to stress, fatigue, or caffeine intake. Common areas affected include the eyelids, face, and limbs. While often harmless, persistent twitching may indicate an underlying medical condition. In some cases, twitching can be associated with conditions like muscle spasms or neurological disorders. It is important to monitor the frequency and duration of twitching episodes. If they become frequent or disruptive, consulting a healthcare professional is advisable for proper evaluation and management.
