There are no specific tests for Parkinson disease. This disorder can be diagnosed only according to the symptoms and neurological examination. Three major symptoms of PD are tremor, muscle stiffens (rigor) and slow movements. They develop slowly not suddenly. You are missing 2 of them. Your age (24) is also not typical for Parkinson disease.
Balance problems (vertigo) can be also found in PD but latter. Vertigo that is provoked by sudden movements or certain body position can be due to so called benign positional vertigo. There are several other reasons for vertigo that should be excluded.
Do you feel vertigo when stand up?
Do you feel nausea together with the vertigo?
Do you have problems with hearing?
Do you take some medicines?
Do you take drugs and alcohol?
