Please don't jump to: Conclusions. A neurologist can make a diagnosis for you. It could be several things, some simple and some more complex. The doc will tell you and help you. Peace and good health.

Tremors: Tremors, or shakes have many causes. Mostly at a young age are what are called "physiologic" and not "pathologic". That means, most are a normal variant rather than sign of any disease. Common causes of tremors include stress, caffeine, nicotine, and other stimulants. If in both hands, that is a symmetric tremor, those are less concerning than those that only involve one side of the body.

Tremor: If not due to hyperthyroidism or a medication, could be you possess heredofamilial tremor. If only tremor, would not suspect Parkinson's, MS, or even Wilson's disease.
