@LittleBird - As @Andy89316 mentioned, there have been a number of discussions about the hyoid & Hyoid Bone Syndrome (HBS) which has some symptoms very similar to ES but also has unique characteristics, too. @a_catindiguise recently had surgery for HBS done by Dr. Dewan in Louisiana close to the same time @F-t had hers in Australia. Below is a link a post a_catindisguise made about her symptoms.
Additionally, the hyoid bone can become “tethered” by calcified stylohyoid ligaments. Normally the hyoid moves freely w/ talking, singing, coughing, sneezing, burping, etc., but when the ligaments from the styloids which attach at the hyoid bone calcify, the hyoid can no longer move as it needs to which can be very uncomfortable. That may be what you’re feeling. Your diagnostic CT for ES should show your hyoid bone as well as your styloids. You can convert it to 3D images using either radiantviewer.com (for PC) or Bee Dicom Viewer App (for Mac) which will make your images easier for you to see so you get a better understanding of what’s going on in your neck. If you do convert them to 3D & want to post a few images here, we can tell you what we see.
