Hi everybody, My tinnitus started in the middle of last August after I went to a birthday party. No loud noises but instead a lot of drinking and cigarette smoking (a habit I have quit since) on a rather cold summer evening in my t-shirt outside. This resulted in a minor cold but a very loud ringing in, then, my left ear. Eventually both my ears have developed a ringing that hasn't stopped ever since. The noises change throughout the day, the sounds that I hear at night are different than during the day. Also my ears crackle very loudly whenever I swallow or 'tense' the muscles around the area of my ears. Is this Eustachian Tube Dysfunction? I am very confused about my condition. Because it's been a (relatively) long time now I have visited an ENT doctor last week but she couldn't find anything alarming in my ears. I now have to come back next week to get a hearing test. Thank you for reading and any replies would be greatly appreciated.
