What are muscle tremors?

Muscle tremors are involuntary, rhythmic contractions of muscles that can lead to shaking or trembling movements. They can occur in various parts of the body and may be caused by factors such as neurological disorders, fatigue, stress, or certain medications. Common conditions associated with tremors include Parkinson's disease, essential tremor, and multiple sclerosis. While often benign, persistent tremors may require medical evaluation to determine the underlying cause.
