I never had ear problems until I was 42 years old. I think its all sinus related which has gotten worse the past two years. Had sinus surgery six years ago which helped reduce the sinus headaches but I still get infections which I think is effecting my ears. I got a bad ear infection last year and my ears have never gotten back to normal, constantly congested and intermittent pain. I'm on antibiotics now but nothing has changed.
