Hang in there. I'm dealing with a 4 week spike since being exposed to crazy amount of pollen. Its felt like a buzz saw. Listen to your ENT if you have ETD/inflammation. That's enough to give you hope it will resolve again. I had no exposure to loud noises, and I think we're probably in the same boat. I know how hard this kind of spike is and how little sleep it can cause! Wish you luck and patience.
