@Zilla - ES can trigger a number of neuralgias because of the cranial nerves it can impact in the neck. TN is just one. Your eye issues & ear problems that exacerbate w/ a change in head position are potentially indicative of vascular compression occurring when your head is in the position that causes them to increase.
What you noted about excessive yawning - that it may be your body’s way of clearing your ears - is a good observation. Ear pressure is controlled by 4 cranial nerves - the TN, Facial, Glossopharyngeal, & Vagus. All of these are prone to irritation by elongated styloids/calcified stylohyoid ligaments. It may be that yawning temporarily takes pressure off whichever of the nerves are affecting your inner ear pressure & thus relieves the pressure.
Utah is one of the states for which we have no ES doctors listed. We had one, but he stopped doing ES surgeries for some reason unknown to us & one other who did surgery for Hyoid Bone Syndrome for one of our members but doesn’t do ES surgeries. We’d love to get the names of some docs in your state who take care of ES but have to rely on our members to provide those for us.
Good idea to talk to the oral surgeon about ES! If you haven’t read over this post made by @Jules, you should prior to consulting with anyone. It contains a list of questions to ask when interviewing a doctor about ES surgery which will be helpful for you. ES Information- Treatment: Surgery
