I think it is urgent that you view a video on the atlas and its misalignment--a good one is this http://www.youtube.com/watch?v=2Ae5CHyS ... re=related
The bone that your jugular is hitting is the atlas--
mine has been misaligned for many, many years--drs did not pick it up when I had accident that affected neck and head, and chiros did not pick it up. So for years, in pain, sometimes severe, affecting head, neck, back--and along the way, optic neutitis, then finally MS diagnosis--only recently, due to bad dental work, went to neuromuscular dentist, and he picked up it was the atlas and CI misalignment that was causing some of my severe symptoms. Was with a chiro, but not getting results once again, so switched (rather than give up as had before), and this chiro finally did an adjustment (not her first try, was seeing her for a number of times) than re-aligned my Atlas--am practically pain free for first time in over 26 years--and my left leg which has been out for all these years is very different immediately. Definitely re-aligned my spine in getting the Atlas corrected. I don't usually hold the adjustments--but this has been for 12 days so far--haven't told chiro yet, see her in 3 days. My theory--couldn't hold the adjustments before, because the Atlas is indeed the king--get that aligned, and rest of sping aligns.
Atlas can be treated by regular chiro manipulations, (might take a number of tries before gets it), or by the very expensive orthoganal atlas machines, which are precise apparently and right on.
I hope this helps you, you have all my best wishes.
