@Jules has written an amazing posts that discusses symptoms of ES - vascular & non-vascular. It’ll be very helpful for you to read - ES Information: Background, Anatomy, Styloid Length, Angulation, Classic and Vascular
Based on the symptoms you’ve mentioned, it sounds to me like you do NOT have vascular ES. IJV compression causes intracranial hypertension (high bp w/in the brain/skull) which causes massive headaches, brain fog, visual changes, sometimes CSF leaks, pulsatile tinnitus & other nasty symptoms. ICA compression can also cause terrible headaches, but the other symptoms are more stroke-like i.e. TIAs, numbness/tingling on half the body or face, neck, intermittent loss of ability to speak clearly, vertigo/feeling faint or fainting, etc. That said, I do agree that it looks like you have a little IJV/ICA compression but it may be minimal enough that you’re not getting vascular symptoms.
