Hi all. I've just joined this forum as I found the posts and people on here very helpful. I've just started to experience t. I don't no what brought it on. Only things I can think of is. I went in the pool on a recent holiday. And went under water. Only to have to come straight back up with water up my noise I think. The pain in my sinus for about 10 secs was horrid. Then I flew home about 4 days after that. And since I've been back I've have a high pitch wine in my head or ears. Also a lower one. Sounds like morse code. I went to my gp. And he checked my ears and nose and gave me a nasal spray called AVAMYS and he has also refured me to an ent. I'm hopeful that this sound will go. This forum is a real help. I'm really struggling with it. I find my self panicking sometimes. I'm trying so hard to stay positive.
