Has anyone heard of this condition? From what little information I can find on the web, this can occur when you have neural foraminal stenosis. The artery gets temporarily blocked with head rotation and extension. The symptoms can resemble that of an TIA(mini stroke). I am afraid I have this and am trying to find more information. I have severe narrowing at C5-6, moderate narrowing at C6-7, from uncinate hypertrophy and disc protrusions and mild thecal indentations at 3 levels. I also have had a few of the symptoms that I have found, but would like to find more information. Thanks.
