Hello. Very Good evening. I'm Dr.Yogesh Kr Sharma. I think its a Neurological Disorder for which you should go for a MRI BRAIN WITHOUT CONTRAST. After the report & films,  kindly come to practo chat for your treatment and counseling part. This is the best possible option for you. Apart from this you can also have a preventive Health check up along with serum calcium and 25 hydroxy vitamin.D report. Don't be anxious and restless, after your investigations, I assure you, we would be able to find Root cause of your bothering. Regards.
