Tremors can happen at any age. They are more common in older people. Everyone has some tremor when they move their hands. Stress, fatigue, anger, fear, caffeine, and smoking may make this type of tremor worse.
A tremor that does not go away over time may be a sign of a medical problem and should be checked by your health care provider.
Essential tremor is the most common tremor. The shaking most often involves small, rapid movements. It usually occurs when you are trying to do something, such as reaching for an object or writing. This type of tremor may also run in families.
Tremor may be caused by:
Brain, nerve, or movement disorders, including uncontrolled muscle movements (dystonia)
You may be prescribed medicines to help relieve symptoms. How well medicines work depends on your overall health and the cause of the tremor.
