I'm not sure if it is the same thing but maybe somewhat similar. I went deaf overnight and sound echoes into and through my head when I speak. Almost like landing in a plane and your ears go deaf. I haven't found a solution so far but my ENT doc said that he thinks my eustachian canals are blocked. If so can anything be done for that? All of these obscure health problems are so hard to live with. I have an appointment to see the ENT again in a few weeks. It's so hard getting appointments lately.
