So I have had 4 separate diagnoses of eustachian tube dysfunction due to allergies. In November, I got ringing in my ears, that was the first tinnitus I got. In December, my right ear began having a low humming noise as well. In early February I got a single, high tone that flutters, sort of like in a morse code pattern. It only happens when there is some sort of background noise. In mid-February this became several different tones that do this. As well as a solid high tone if I'm around anything with a motor, like the fridge, or something like that. When there is silence in the room, I don't hear the tones. It's ONLY when the heater is running, or any type of electronics device is running (air purifier, etc.) As soon as silence happens, the T is gone. I have tried googling this and haven't come up with much. I don't understand why my tinnitus has changed so much. I agree with the ETD/allergies diagnosis, this winter my allergies have been worse than ever before, and I've had ear pain and pressure, and popping. It seems like every time it's gotten really cold this winter, my ears hurt more and tinnitus gets worse. I have indoor allergies (mainly cat) and it makes sense that when it gets colder, the heat runs more and stirs up all the dander in the house. Also, whenever my ears are bad (hurting, pressure), I've also had a muscle contraction in my left ear that happens in response to loud, sharp sounds. When my ears settle down and aren't hurting & feeling pressure so much, this lessens. Have been dealing with PTSD from something that happened in 2015. Have had more anxiety that I've ever had in my life. When the T arrived (and with each change of it), that has also caused high anxiety. Any insight into why my T has gotten reactive and more sounds have developed would be appreciated!
