For The Last 2 Weeks I Have Been Feeling Dizzy

For the last 2 weeks I have been feeling dizzy like coming off a roller coaster. I am fine when laying down, but not flat. When I get up and move around I feel dizzy again. On occasion I feel shaky in my hands. I have been to the ER and my blood work was fine and my EKG and blood pressure was fine. Before I felt this way, my family drove over a couple of mountain passes and back. I thought it was an ear thing. I had a lot of wax build up and had my ears cleaned out yesterday. I was ok until a little bit ago. I felt it come back.
