Connective tissue, sometimes called fascia, is a continuous web running through your entire body. It wraps every muscle, surrounds every organ, sleeves every nerve, and connects your shoulder to your hip and your jaw to your breath.
Healthy connective tissue glides. Layers slide over one another easily, allowing movement to feel effortless and unremarkable.
After injury, long-held tension, inflammation, or simply years of the same posture, that gliding can become restricted. The tissue thickens and organizes itself to protect. It is doing something intelligent — but when the restriction stays, movement narrows and comfort fades.
This is why a problem in one place so often shows up somewhere else, and why treating only the loudest spot may bring relief that does not last.
