Have not experienced this but may I suggest that you work with the ENT for the meantime. Possibly also get an second ENT to look at it.
She sees her first ENT on Monday. That was the soonest she could get in.
The audiologist she saw today actually has a PhD in the field and she seemed to be pretty sharp according to my wife.
The problem I have is my wife is by herself in California as I work in Alaska full time. So I only get the information second hand.
