Maybe not confused - I have read pages 1-6 of this thread and there are a wide range of people on here looking for answers. Not just pilots and some with differing conditions and symptoms.
There are various posts of advice - good and bad. Get expert medical advice before trying anything you read online.
Your right, have it checked by a GP or ENT.
I'm guessing most of you have and that's why your looking for answers online!
This is just an example of what works for me... and you should only do if your GP is in agreement.
My ear was caused by blowing my nose to hard, too much pressure caused my ear to become damaged inside. Now my ear is damaged all kinds of things irritate it and becomes trapped inside causing fluid to build up.
It may be just a theory but could too much high altitude flying cause a similar problem due to the frequent poping of the ear?
