I have had this problem for almost 4 years now . I was just riding down the road and my right ear shut off , never to come back on. Went to two ENT doctors . Sudden sensoral hearing loss was the diagnosis. I wasn’t sure they really knew. One said a cochlear ( might) help. I need a little more than might! I get along well most of the time. The facial numbness and the inability to tell the direction of sound is the most aggravating part. Sometimes my face , just on the right side , feels like no just left the dentist.
