General question here. I am a 26 yr old male and i work in an office where i type. I am healthy as far as i know, my only concern is for years now I have noticed i can not hold my hands straight out without my fingers twitching or shaking. It is like a slight shiver. If I put my hand down and type it does not happen, only when my hand is flat. I noticed this through typing at my job. It gets worse if im nervous, (holding a paper in front of a crowd) but i constantly have lightly shaking fingers. What could this be? Any reason to worry here? thanks a lot.

Do you drink coffee or caffeine products such as Coke?

If you are not a heavy user of the above you should talk to a doctor to rule out medical problems.
