Thanks for writing in to Healthcare Magic!
If you are aged above 50yrs and there is history of Parkinsonism in the family then it may be a possibility.
Otherwise also it may be a harbinger of some neurological problem and must be rule out.
You should get complete neurological examination and investigation to detect a cause because such presentation may be due to tumor
, vascular anomalies, problems with circulation in brain.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
