Suggest Remedies For Persistent Problems In Right Eustachian Tube

Hello, I was having problems with my right side eustachian tube, for many many years now, it basically make it hard for me to breath normally or to focus on study or any task. It has my life really difficult, and the long list of problems that comes with it too long to mention here. However, I read once, on a forum, that this may be caused by wheat allergy, so I stopped eating anything derived from wheat. Since then, it has been one month now, I feel that I am getting more and more normal . And I feel much better. I was wondering if it is a known problem in the research community, and if there is any study that established a link between the mentioned cause and effect.
