Sounds like a pretty good PT person so far..

Checking and mobilizing the first rib, is what it sounds like to me.
My chiro, the adv PT guy & the PT teacher all did it a few different ways for me, but the idea is the same.

I hope he does check around for Trigger point also.

It was a multi pronged approach that worked for me.

reduce the spasms
resolve as many trigger points as possible
drop the top rib/s back into place


I did most of the posture work at home
but chiro adjustments really helped with the forward head/shoulders & the hump at the back of the neck area..
