Tremor (uncontrolled shaking of a part of the body) is a common symptom in Parkinson’s and is caused by the lack of the chemical dopamine in the parts of the brain that control movement.
The typical tremor in Parkinson’s usually happens in a part of the body which is inactive. It may first be noticed by somebody else. Some people may also experience tremors when they are trying to do something like holding an object or taking a drink. Not everyone who has Parkinson’s will have a tremor and there many other conditions unrelated to Parkinson’s that can also cause tremors. A specialist will often be able to tell the difference by examining you.

Will my tremor get worse?

Although Parkinson’s medications can help, Parkinson’s tremors do tend to get worse over time. For most people, the worsening of tremor is a slow process that occurs over several years. As time goes on, you might start to notice that your tremor spreads e.g., from the hand to the arm or from one side of your body to the other. Some people also find that their tremor starts to affect their jaw or lips, and some describe feeling an internal tremor where they feel shaky on the inside although other people cannot see them shaking. Many people with Parkinson’s report that their tremor is not constant and the way in which it affects them day to day changes too.
