Tremor is an involuntary shaking movement that is repeated over and over. Although it may affect any part of the body, tremor most often affects the hands and head. Your voice may also shake. Sometimes the feet or torso may also shake.

Essential tremor, which sometimes runs in families, is one of the most common types of tremor. It is shaking that is most noticeable when you are doing something like lifting a cup or pointing at an object. The shaking does not occur when you are not moving. Medicine can help reduce the shaking. Brain surgery can be helpful in some cases.
