@BraveKat - Most of our members who have bilateral IJV compression have found that getting both sides decompressed is necessary for optimal resolution of the symptoms that vascular compression causes. Whether or not the styloid is involved w/ the remaining IJV compression, you may need to get it decompressed.
Was there any comment made about your hyoid bone or thyroid cartilage as they appeared in your CT image(s)? It seems radiologists often only look for the things they’re asked to evaluate & ignore other things that may be amiss. The cracking sounds you’re noticing can be caused by calcified thyroid cartilage &/or elongation of the greater horn(s) of the hyoid bone. Perhaps you should look into Clicking Larynx or Clicking Hyoid Syndromes. We’re in a thread where Clicking Hyoid was addressed, & here’s a link to one about Clicking Larynx.
This is possible. I gather you have no stylohyoid ligament calcification on this side either?
The vagus nerve exists on both the left & right sides of our bodies, but more dominantly on the left so it could be the section on the right side that is continuing to cause problems; however, your suggestion of waiting 6 more months to see how things improve is a good one. Symptoms can take a year or more to fully recover & the recovery process can be frustrating as the months creep by w/o significant gains. The victory comes after all those months of patience when one realizes the symptoms are gone or mostly so. I will keep praying that your body is healing, just slowly, but that you’ll begin to notice more substantial & longer term improvements.
