Tremor (shaking), slowness of movement, rigidity (stiffness). Tremor (shaking) is one of the common symptoms of Parkinson’s, alongside slowness of movement and rigidity (stiffness). Not everyone will experience all of these symptoms.
For some people, a tremor can be the first sign of Parkinson’s. However, having a tremor doesn’t always mean you have Parkinson’s as it can be caused by other conditions. Not everyone who has Parkinson’s will have a tremor.
