What is the reason why my hands are shaking?

ANSWER

Essential tremor (ET) is the most widespread disease of the nervous system. It usually starts in your hands, but it can move to your arms, head, voice, or other body parts.

ET is different because it affects your hands when they’re already moving. Most other forms of tremor take place when you’re still.

It could result from a change in your genes (your doctor may call this a mutation). That means if one of your parents has a tremor, you’re more likely to get one, too.
