I am unable to work for a long time. And after a long time of working my brain feels to be empty and very light in weight. when I tried to take a sleep then I am unable to take a deep sleep and a while trying to sleep I have a vibration like feeling in my whole body including head, thus I am unable to go for good sleep. When I press the back side of my head slightly then it feels quiet relaxable and slight pain full kindly suggest me any diagnostic or medication all type of physician whom to consult.
