I just noticed last night that whenever i use my hands, the shake and i can't make it stop until i stop using my hands; ( gripping, picking up things) ?

Intention tremor: Try not to get too scared by the info at wiki. See a neurologist to evaluate & treat as well as they can. Often it is like an essential tremor and gets no worse or much better. That's not very pleasing, but may be true. Here's a link for info (again, don't get too scared): http://en.Wikipedia.Org/wiki/intention_tremor a specialist psychotherapist might help you adapt to whatever it is. Best wishes.
