I just got an MRI of my upper chest (sternoclavicular joint) ordered. They said it's not a typical MRI which is why I have to wait until August. I'll be evaluated for hypermobile EDS by an orthopedist. I want multiple stabilization/reparative surgeries, and what do I need? Not sure. The eustachian tube dysfunction /snapping hyoid can be affected by swallowing. The hypermobile hyoid and posterior SCJ subluxation cause airway irritation, making me react to things such as smoke or fragrance more easily.
