Essential tremmor, well, maybe. Usually ET isn't too bad, but in severe cases, it can be disabling, because the person shakes so much that it's hard to do normal things like pour a cup of coffee or quite difficult to do other things with your hands. If it bothers you or limmits your capabilities, you should seek medical attention about it. The doctor of choice is a neurologist. Medications
can be used in treatment as well as support. The most extreme measure that doctors will suggest for treatment is brain surgery. A type known as DBS or Deep Brain Stimulation, where surgeons drill a hole in the skull and implant tiny electrodes in the brain, the movement center, (Basal Ganglia, sometimes the thalamus or sub-thalamitic nucleus or some such thing)
and when in the right place, the electrodes are attatched to an electricity-producing 'stimulator' that when turned on, should relieve symptoms by changing the impulses in the brain that cause the tremmor. It's very expensive and certainly not recommended except in the most extreme and debilitating cases. I know about all this stuff because I'm researching DBS for my own movement disorder, which has become impairing.
Go to Wemove.org and look at Essential tremmor. Other reliable sites would be CDC, Howstuffworks, Mayo clinic and other sites. Look it up, see if your symptoms of tremmor seem to qualify. Essential tremmor used to be called 'benign essential tremmor' but in recognition of the debilitating nature of the severe cases, the 'benign' was dropped.
