I need help figuring out what may be causing these symptoms:
Over the past year I have had fullness and pressure in my left ear. when it releases I hear hissing in that ear and I get vertigo. This lasts from 1 to 4 minutes and I get these "episodes" any where from 4 to 8 times a month,somtimes more. Over the past couple months new symptoms have arisen. Now when the pressure releases I have a loss of coordination, I cannot focus my vision and I get nausea. What might be causing these symptoms?
Thank you.
