Hi, I have had PT diagnosed in my right ear for nearly two years. Two months ago it started even louder in my left ear. It now prevents me from sleeping properly which is effecting my husbands sleep too. Should I assume that it is also PT? Getting very frustrated and low, I can even hear and feel it whilst watching the TV as it is now a off centre whooshing in stereo in my head! I had the Doppler scan on my artery for my left ear and camera up my nose and down my throat. Also I had an MRI before my diagnosis for my left ears PT. Has anyone else had PT start in one ear and the occur in the other at a later date? many thanks - Leah
