@Jules put together a series of posts with answers to many questions about ES. Each one starts with ES Information: If you type that, or paste it into the search box, all her posts will come up. I’ve included links below to the two which are most likely to help you. You can save them to use during a consult.
I truly don’t know how many doctors know the number of cranial nerves ES can affect & which symptoms tie to which nerves. I’m sorry to say I think you’ll be hard pressed to find an ENT who is completely informed in that arena.
