Ask a Neurologist and Get an Answer ASAP
Do you have a tremor? Problems with your gait or balance? Do you have any difficulty initiating movements or moving more slowly than before?
These are some of the features of Parkinsons. The diagnosis is made based on history and physical exam.
I would suggest you ask to see a neurologist. While unlikely to be PD, he can check you for this and get you started on the appropriate medication, if necessary.
