I want to update that my chiro did some nimmo for my severe spasms (mix of soft/deep tissue/trigger point etc), and top rib mobilizations, as well as adjustments and upper cervical adjusting (c1 c2).

The usual treatment went like this -
attached the IF stim pads to my shoulder/upper back on each side and also lower back each side and turned it on
then used ultra sound on my c spine and upper back
some times if specific pain areas he would use the soft/cold /low level laser - like on my wrist, elbow, shoulder and low back when it needed (I will buy one of those when prices come down, it is great and tx time is quick)

then adjustments if needed
went 2x a week for about 2 months, then weekly, then monthly for maintenance when symptoms were under control.
