Tremor in Left Leg
My uncle is 75yo, 3 years ago his left leg begins shaking on its own while he is sitting watching tv or driving. Once he becomes aware of this or once he moves his leg ever so slightly, the shaking stops. When he is under stress, the shaking becomes more frequent. It only happens occasionally in the beginning, but recently it’s becoming more frequent. So far it has only affected his left leg. Another symptom is when he is holding a heavy object, like a bottle with his left hand, his hand/arm would also start shaking. But unlike the left leg, the hand never shakes at rest. May I know what condition does he have? Anyone with similar symptoms? Please help. Thank you.
