There’s info in the Newbies Guide Section about different symptoms & possible causes; if you have a read of that it does explain what vascular symptoms are in more detail (briefly, dizziness, fainting, head pressure, ear pressure, pain in the eyes, pulsatile tinnitus). Here’s a link:
ES Information: Common Symptoms And Possible Explanations For Them - Welcome / Newbies Guide to Eagle Syndrome - Living with Eagle
ES Information: Background, Anatomy, Styloid Length, Angulation, Classic and Vascular - Welcome / Newbies Guide to Eagle Syndrome - Living with Eagle
Hope this helps!
