I had suffered from acute otitis media in both my ears a few months back. It has resolved however, whenever I yawn or swallow I hear loud clicking or crackling noise in my ears. This sound can also be heard by someone who places their ear very close to one of mine. I'm also having whistling tinnitus in both my ears. Doctor says I'm having eustachian tube dysfunction. May I please know what is the crackling noise due to? My doctor says there's no fluid in my ears. Will these ever go away?
