Eustachian tubes, rhinopharynx and throat symptoms for over 3 months

I found this website looking for answers to what I have been struggling with for the last 3 months. I have never had ENT problems before in my entire life. I am 38 years old and out of the sudden on January 8th my life changed and my ears, nose and throat never felt the same as they used to. This was from a moment to another. I was not on a plane, I did not have the flu, or allergies or anything. I was perfect and then suddenly I wasnt.
It all started with a diffused pain/pressure under both my ears and then the next day I felt it also in my front neck… dont know how to explain but it was all my front neck. Like if the lymph nodes from my neck where hurting from inside. It was not the muscles but like the internal part of the neck sorrounding my throat and under my jaw. In the physical examination the doctor could not found any of the nodes I felt inside and it also did not show in the ultrasound. Everything came out normal (this was on january 27th). Also they run some lab test and they were normal. I had my ears tested and my hearing was also normal but the results for my eustachian tubes came out with problems. They are not functioning well. By this point I had been experiencing also both my ears popping (left more than right). One ear felt pressure and then got blocked as if I was in an airplane and then it opened and then the other ear… and so.
This began to drive me crazy, also because I could here the echo of my voice everytime one gets blocked. I also began to feel the perception of my own voice was not normal. Like when you have laringitis and you feel certain nasalness (dont know how to explain it). But there is certain “shine” in my voice specially when pronouncing nasal letters. Then I began to feel like the back part of my nose (rhinopharynx) was swollen (I feel it when i talk and when I breath out of my nasals). Then that weirdness of my rhinopharynx felt also in my throat in both sides like just above my tonsils. And then it felt like real pain. Sometimes I feel weird when I swallow my saliva (liquids and food feel normal). And sometimes I feel like if I had something stuck in my throat.
I just want to feel healthy and normal again. Dont know what is going on inside of me. I will see the doctor again on april 16th. But I have trouble functioning well daily because i feel all this symptoms and I get anxious and worried. I forgot to mention my doctors treatmet was nasal spray (steroid) and then 1 injection that was supposed to be stronger but neither worked.

I am losing my mind….
