About Two Months Ago I Felt A Woozy Dizzy Feeling

About two months ago I felt a woozy dizzy feeling when exposed to loud noise and bright lights. An ear specialist said it may be a disconnect between my inner ear and my brain. He prescribed a vitamin called Lipoflavonoid. Not sure if that will help but I have been taking it for about a week. Now I am feeling heavy pressure in my chest, and my ears feel blocked mostly on the bus when I leave work however I am now feeling that during the day as well at work after lunch. I also feell lethargic and hard to concentrate at those times. Also feel slight tingling in my head and arms when the feeling is too much causing anxiety. What could be causing this and what should I do?
