I bet i have knots here too
I have them all over my back but i think theyre latent trigger points. My serratus anterior has knots and theres barely any muscle!!

Def on board with the fascia theory after my experience with my pec minors

People with one side of their rib thats constantly elevated need to look at their lower body or mild scoliosis. My left (elevated rib side) leg appears shorter and i walk with a slight limp. Ive gotta figure that out
