I have been doing some research and am pretty sure I have chronic eustachian tube dysfunction (ETD) in my left ear. For a few years, my left ear has felt full and I constantly yawn, vasalva, etc. to try to get temporary relief. However, I've never had ear issues on planes. Is this a disqualifying condition? I imagine this might raise questions if I want to be an aviator down the road, but I don't see why it would be a problem in other jobs. Would you recommend that I see a doctor to diagnose the issue before I go to DoDMERB? I am considering waiting because I feel as though getting an ETD diagnosis from a doctor could cause issues at DoDMERB.
