did you ever end up getting prolo?
I realize this is an old thready, but I just stumbled across it and have very similar symptoms as you have described.
I was in a car wreck back in 1998 and hit a tree backward fairly hard. I never seeked treatment or experienced much pain following the event. Well, a few years later, a friend and I were horse playing and he got me in the headlock and squeezed pretty hard. From that point on, Ive had a popping sound in my neck everytime I turn it to the left or right. At that time I had no symptoms, just popping/grinding noise in my neck.
So, here I am many years later dealing with pressure in my head, headaches at the base/sides of my skull, visual snow/floaters, nausea, neck pain, intermittent anxiety attacks and arm tingling.
Ive had all sorts of tests from blood work, mri, catscan of brain and cervical spine, seen neurologist, ents, opthalmologist, etc... to no avail.
I read up on Barre Lieou Syndrome myself and was going to look into prolotherapy to see if I could find relief.
Do you have any updates on your situation?
