Since more than a year, I have been feeling vibrations in the left side of my head and behind the ear. Have been to multiple physicians and was always told that it is due to migraine. After eating the prescribed medicines, the vibration like feeling goes away. But as soon as I stop eating the medicines, after 1 or 2 months the vibration start again. It is very irritating and when my environment is quiet I feel it more and it is very evident as if some train is running.
