I have ringing in my ears. I get extremely dizzy if I lay on my back and tilt my head backwards, more so on the right side. For example, if I try to lay down to look under a car, I get so dizzy that i feel that I am going to get a heart attack, so I am literaly scared to try and do any work on my care. I am healthy, take no medications, I am 82 yrs old. My email is YYYY@YYYY in Brownsville Tx
