What it means
A tremor is an involuntary, rhythmic shaking of a body part, most often the hands. Rest tremors occur when the limb is relaxed; action tremors occur during movement. Essential tremor is the most common type and often hereditary. Parkinson's disease classically causes a resting pill-rolling tremor of the fingers. Other causes include hyperthyroidism, medication side effects, excessive caffeine, alcohol withdrawal, anxiety, and low blood sugar. Most tremors are not life-threatening, but a doctor can identify the cause and offer treatment. Tremors that appear suddenly, worsen rapidly, or accompany slurred speech, weakness, or loss of coordination need urgent evaluation.
