I am not totally up to date either. There is Bolognese on Long Island, Patel in SC, Henderson in MD/DC. I have a sense there are a couple more people doing CCF in the US in the last few years, but I can't recall names. And then abroad--Gilete and Hernandez in Barcelona (two practices, now, I believe) and also someone in India who I have heard is reputable.
Bolognese is the one who did Jen B's and Jeff W's (have you looked at his website?
https://forums.phoenixrising.me/threads/connective-tissue-problems.56788/ in case you haven't seen it) surgeries, and I think Jeff still works with him on patient navigation or something similar.
Did the Atlas Orthogonal help with the psychological/mental stuff? It is so complicated--all the bits and pieces that need to co-exist and thrive in that small area of the body.
I haven't done much for my neck since being told I was well off! Sometimes I wear a stiff collar when I have a flare, I use ice on my neck whenever things get bad and that is super helpful (indicating some sort of swelling or vagus nerve dysfunction I would think), and then as mentioned, I use traction.
Traction clears my mind, sharpens my eyesight, lowers my heart rate. I can pinpoint the moment when things shift because my vision shifts into clear focus. For ways to test this out---I used to just pull up on my head and I would feel a bit better. When I was driving and felt awful, my daughter would reach over and lift my head from the passenger seat and I could access enough energy to complete the drive.
I also got a couple of collars as means to trial some manipulation to my neck. I have the Aspen J, I think, which is pretty stiff. And a Philadelphia, which is less so, but still gives some support. The Aspen lifts my head a tad and so I can tell--this helps. My cognition, my energy, my pain, my heart rate.
And I suppose you could order the Saunders or
this one, which is actually the slighter cheaper and PT-approved model I have, see if it brings you any relief and return it if it doesn't?
Just some thoughts about how you could get some real life feedback that might help point you toward the next step.
