Hi..., your symptoms are suggestive of essential tremors... Essential tremor is a nervous system (neurological) disorder that causes involuntary and rhythmic shaking. It can affect almost any part of your body, but the trembling occurs most often in your hands ... Avoid caffeine. Caffeine and other stimulants can increase tremors.... Learn to relax. Stress and anxiety tend to make tremors worse, and being relaxed may improve tremors.
