While parkinson's disease
does have a "classic" or "typical" set of symptoms, these symptoms can also be caused by drugs, toxins, trauma, etc.
The only way to determine whether you truly have parkinson's disease is to see a physician (e.g. Neurologist) who will ask you about your symptoms and perform a physical exam to see if your symptoms are consistent with parkinson's disease.
