Not a big fan. Only been to 3 in my life. 2 just once and a third - I gave her 4 tries. The first one timer was when I was a teenager. The guy just spooked me.

The 2nd one timer was more recently. I was encouraged by my doctor as a possible solution to what has become a chronic (7 months) of intense upper arm pain. Not rotator cuff nor bursitis - no supporting symptoms. It remains a mystery and so I will be off to a Orthopedist soon for his assessment.
Anyway, the CP asked me a bunch of questions. She never touched me or asked me to remove my shirt. She just looked at my back. Decided I had some misalignment, showed me some exercises to do, printed out some instructions for me to take home and told me to come back in a week. I told her I couldn't do the exercises because the pain was to intense. She told me to "
just try - do your best".

The one I visited 4 times for a lower back problem, would have me come in for a few minutes, she would clic my back with some device that felt like she was snapping me with her finger, and she pushed here and there. She suspected a disc issue but never requested X rays. Just seemed intent on having me come back very week for a year or so. I did not see (or feel) the benefit.
That's all I have to say on the subject. Not very useful - my report or my experience. I hope others may find a CP more helpful.
