Described below is one of the many approaches I've tried or considered trying for healing my chronic myofascial pain:
BOTTOM LINE: Most likely helpful to moderate symptoms; however, I haven't yet seen major improvement.
Poor posture can be a sign of a body out of alignment. Over time, poor posture and poor ergonomic conditions can cause tightening of muscles and fascia. Whether or not poor posture and poor ergonomics cause myofascial pain syndrome, they certainly can exacerbate pain symptoms. At a minimum, I have found that paying attention to posture and proper ergonomics slightly helps to moderate my symptoms. However, I believe these are likely only small pieces of the puzzle as a cure for deeply embedded, emotion-fed myofascial pain.
I try to work on better posture to reduce stress on my myofascia and trigger points using the concepts in Esther Gokhale's book 8 Steps to a Pain-Free Back: Natural Posture Solutions for Pain in the Back, Neck, Shoulder, Hip, Knee, and Foot. However, I haven't seen any major change in my pain, although admittedly I haven't strictly committed to this. I read the book and went to a free workshop in 2015, and while I am more conscious of my posture, I haven't eliminated my remaining neck pain.
