Tremor

Today I wanted seriously see what and why this happens to me.

I have tremor for a long time  in my face ... its a minor one .... and I do not know that this is the word for it as well.

What is Tremor

Tremor is an unintentional, muscle movement involving to-and-fro movements of one or more parts of the body. 

It is the most common of all involuntary movements and can affect the hands, arms, head, face, vocal cords, trunk, and legs. 

Tremor can be  a symptom of another neurological disorder.
