What you see “bulging” in your picture certainly looks like your right SCM, @Dizzy, so what @IvdM is suggesting about his own case may be applicable for you, too.
Our member @wolfjohne22 just posted about his disappointing appt. w/ Dr. Patel, but in his case, I think it’s good that Dr. Patel declined to help him because he may have vascular ES with IJV compression. With the symptoms you’ve mentioned, that might not be a problem for you in which case Dr. Patel would be a good surgeon for you to see. ICA compression is more straight forward to address because it’s usually lower in the neck. I only mention wolfjohne22’s story as it’s good to “expect the best, but be prepared for the worst” in any doctor’s appointment. When one door closes, another will open.
