Hi
@Jas888
Welcome to TT! Glad that you have found us - a lot of people struggle with T and this site is often very helpful.
I am quite surprised at your audiolgist's attitude. For starters, he may have T (tinnitus) but his was most certainly noise-induced because of his time in Vietnam. Yours sounds like it is due to a pressure change/sinus related. Can I ask, have you had a cold recently? Sometimes if you have a cold and fly this can cause problems with your ears.
Don't despair. He is right in the sense that there is no cure for it, but did he tell you that T can go away? I think was a lot of people T leaves - however, this can take months. I can't say for certain that yours will leave - I wish I could say that everyone's would leave - but you have only had yours for 11 days. There is plenty of time for it to go away. I would not consider T permanent until you've had it for at least 2 years - and even then it can go away for people.
Time is your best friend. Unfortunately there is not much else you can do. Have you asked for a nasal spray? Sometimes that can help because it forces your eustation tubes open, but bear in mind that these sprays can take 6 weeks to start taking affect.
Try not to worry. There are links between tinnitus and anxiety, so the more relaxed you are the better. Easier said than done, right? But just keep telling yourself that it will go. I think that if we tell ourselves that our bodies will pick up on the message and fix it. As said before, 11 days is nothing. Your T could easily go away.
Let us know how you are getting on!
