Hi Valerie,

I was thinking about your high collarbone and the choke/strangle feelings you mention.

It could be that your SCM and/or scalenes are spasmed and pulling on the top rib and clavicle.

our stickys have many more anatomy & trigger point links-

Does your osteo do top rib mobilizations as well as other therapies to release any triggerpoints and relax those muscles?

I had some severe spasms and my chiro did something called NIMMO {combo of deep stretching and triggerpoint release}, IF stimulation, low level laser, top rib adjustments and of course other adjustments as needed since the spasms pulled things out of alignment at times.
