Hi, I am hoping for some advice re a possible blocked Eustachian tube for several months now. A test showed my hearing is normal, but I am experiencing periodic crackling in my right ear. When I blow my nose nothing is ever produced from the right nostril. I can t pop my right ear when holding nose and mouth and blowing out. I ve tried yawning, swallowing, chewing gum, non prescription decongestant nose drops. No significant ear problems or surgery. Hearing tester did say my ear canal looked narrower than normal. I had tonsils removed in childhood. I am 67.
