Hello everyone, In recent months many things happen in my life so it makes for me harder to figure out why i do have a ringing in my ears. In the April i attended the audio show where you go from room to room and listen to different speakers. After the show I did not have any problems. Not even ringing effect after the show. Later, on May the 8th I went to dentist and I had my tooth prepared for the crown. It turned out to be a disaster and I had so much pain that few days after I had the root canal done on the tooth. (it is the top tooth in the back on my left side very close to the sinuses) The root canal was another disaster, I had so much much pain after it that it took almost 1 month to decrease but the sensation of foreign object and trauma in the gums never completely went away. The dentist checked my tooth and said that all was done perfecty and I should not worry about it and that some people are sensitive and it might take longer for the gums to completely heal. On June 12th I went to my dentist again to triple check everything and i was told everything was good. While all this was happening I was in the process of doing a research for my new audio amplifier. I went to best buy two times (5/22 and 5/27) and listened to different equipment and speakers. Most of the time the levels were between 80-100db and my session there lasted about 1.5H each with breaks and discussions between songs. What i remember that before going for the second session (5/27), my dad came to my house and before we left I told him that I just started to hear ringing in my ears. 5 minutes later it went away. Also, during the same time frame I tested my self with the tone generator for my hearing frequency range. I was able to hear up to 18400Hz. On 6/10 I received my new equipment. The sound it was pro ducting was not appealing to my ear. The hi tones were too bright and annoying. I did not like it. For me it felt like it was hurting my ears although I was not loud when I was listening to it. (75-80DB SPL) Next day i listened to it with my dad and we both agreed that the sound was not appealing and hi tones were too strong and not easy on the ears even at low volumes. It had lot of a sensation of squeezing car brakes. I did not listen to it much as I decided to return it. On Friday the 13th I turned it on for the last time and listened to it for like 10-15min before packing it. Once finished, I turned the equipment off and while nothing was playing I looked at left speaker while I was collecting my thoughts and then the ringing got activated. I went for a walk thinking it was nothing. Unfortunately it never went away. I woke up with ringing and since that day I could not fall in sleep for 6 days. I have been reading a lot trying to figure out what happened. All was leading to tinnitus. On 06/17 I went to see MD to check for any possible ear infection. I was told all was good. I was prescribed simple decongestant and Fluticasone Priponate nasal spray for possible Eustachian tube dysfunction. I did not noticed to much of the improvement. In last few days i did few experiments. I did a lot of neck massaging as it always feels stiff due to my computer related job. I also tried to use my inversion table. What I noticed that after massaging my neck and using the inversion table I was able to turn the noise off in my right ear for one night. Not sure how all this relates. I am trying to give as much details as I can so please forgive me if I wrote too much. Today, I tested myself with simpe equalizer (fade low frequencies) to see if I still can hear ok. Seems like my hearing is as good as it was before. Sometimes I feel like i can even hear more. My ears are very sensitive now to high frequency sounds like sound of the car brakes, etc., but the ringing continues. Sometimes it feels like it is associated with clogged ears feeling. Sometimes the tone pitch changes to higher, but most of the time it is a very high frequency tone. similar to the one you get after being exposed to high volume sound but lighter. To fight it I do listen to water sounds while trying fall into sleep. Sometimes i get feeling that it goes away and once i realize that its not there it comes back right away. But i cannot control it and when it goes away it just 1 second or so and happened to me only 1 or 2 times in the morning after waking up while i was reading some article on the phone. Few questions: - did i develop tinnitus - can this go away after few weeks or months - can this be related to my tooth problem i had before - can this be related to my neck stiffness - should i go to ENT or its better to wait some time before i go - if i do hear still good can i still have tinnitus - could there be a relation between root canal and sinuses and ringing I am afraid that going to another doctor will just put me in never-ending loop with no solution. Any advice would be appreciated. Thank you.
