I had some loss of the normal curvature mentioned often by PTs & chiro.
Also mentioned was flatness thru T spine area.

Most notable changes happened w/ chiropractor - lost much of the noticeable C/T area "hump" also.

Some improvement was from resolving trigger points & spasms as well as the adjustments. My chiro did the manual TrP tx as well as txing the myofascial issues.

PT & DC both tx'd the raised top rib issues too.

Al these pieces of the TOS puzzle....tricky to figure out since we get varying sx and causes. Mostly trial and error to find what works best for each of us.
