It may be during an investigative phase when the probable group of disease has not yet been determined. It may be that you have tremors, but not just tremors (which is typical of Parkinson’s disease) but other forms of tremors (in movement or position), and stiffness. This is not enough to meet the diagnostic criteria, but the suspicion that it may develop further remains.
There may also be symptoms that may be caused by medicines and that “Parkinson-like symptoms” may occur after starting a particular medicine.
It is most likely that this is at an investigative stage and that one needs to follow these developments to arrive at a definitive diagnosis.
