7 month post corset plasty/SMAS unbearable tightness. PS recs myofascial release, why? Way to treat?

7 month post corset plasty/trad. Neck lift. Had hematoma & seroma post sx day 1. Healed nicely. So see no connection. Growing tightness-sticky duct tape pull feel when turn neck. Feels like unremitting vice. Ps recs myofascial release tx. Primary MD instead recs PMR & Neuro. Can adhesions w/in the tissue layers occur? What would be non-visual physical symptoms of myofascial adhesions? What will myofascial therapy do for my intense tightness? Thank you.
