About 4 Weeks Ago, I Started Getting Dizzy In The

About 4 weeks ago, I started getting dizzy in the morning when I sat up. Now it happens every time I move to fast. I see trails and then my eyes do a shutter thing and I have to be very still and then move very slowly. Seems to happen most when I am in a sitting or laying down position and then reverse those positions. I do not take any medications. I am a white, 56 year old female.
