Hi,
Possiblity of essential tremors are very high,secondly it could be hyperthyroidism.Although
essential tremor can affect almost any part of your body, trembling occurs most often in your hands, especially when you try to do simple tasks such as drinking a glass of water, tying your shoelaces, writing or shaving. Sometimes, you may also have trembling of your head, voice or arms.Family history and age are risk factors.Its a benign condition without underlying pathology.
