I can’t help you. 
But just wanted to ask…why are ENTs so inempt at removing wax from the ears?
One time, when my daughter was young and had a tubes in her ear, the ENT we were seeing kept having us come back because he couldn’t see if one of the tubes was still in her ear drum. Eventually, (after getting several pmts from the ins. co.), he told us to go to our family doctor and have him flush her ear out (for wax). Now, wouldn’t you think the ENT would be the perfect person to flush out an ear? I did take her to the family doctor, and if I recall right, the tube came out (it was due to have come out) with the wax.
I know “regular” doctor’s can’t see the eardrum well with their scopes, but ENTs should have the proper equipment. Another ENT I’ve been to had a set up where he could put something down her canal and see the eardrum magnified.
Good luck in finding out what’s wrong and I hope it isn’t serious.
