@EagleRay - we have several members who are good at reading CT scans & MRIs to some degree. If you upload your scan(s) to dicomlibrary.com, the site will anonymize them & give you a link to share either here on the public forum or with specific members via private message. That might be the best way to get a more accurate evaluation of your scan(s).
Have you tried getting an appointment w/ Dr. Cha for evaluation for ES?
