@4alien2 Do you have any issues with your jaw? https://www.healthcentral.com/article/tmj-eustachian-tube-dysfunction-issues
@4alien2 I was just reading your profile, if the ETD was caused by acid refux or GERD, then treating this as the underlying cause should eventually help your ETD. https://www.medicalnewstoday.com/articles/gerd-nausea#prevention
@4alien2 I am going to do an allergy test and I'm waiting to see my ENT consultant and a Jaw Specialist.... I think it's best to tackle these issues from multiple directions.
