I have not been diagnosed yet, am seeing ear nose and throat DR in 3 months.
I have the tinitis in left ear only, basically all the time now, and in perfect timing with pulse. For me it is quite quiet, in fact I do not notice it at times. Mine gets very loud just before I have a dizzy/balance spell, followed by nausea for the remainder of the day. Hearing comes and goes in left ear only but, never total loss of hearing.
Meneires and Labyrinthitus seem to be very similar in my research. Also Lyme disease has some similarities.
