Am I developing parkinson's disease?

Hi, for the past year I have started using my phone excessively and playing games like Color Switch for hours on end didn't help. When I lift my hand, my thumb starts twitching and shaking more than anyone else in my class. If I lean my head on my hand, my arm will start shaking. Is this Parkinson's disease, something else, or nothing to worry about?
