Fascia is connective tissue that wraps around and supports structures throughout the body. It is rich in collagen and exists in layers with different roles, from tissue beneath the skin to tissue around muscles and organs.
A network, with local detail
Thinking about connections can be useful, but individual structures still matter. Fascia, muscle, tendon, nerve, and joint are not interchangeable words. A body map is an invitation to learn about an area, not a way to identify the cause of pain.
Start with useful questions
Where is the area? What structures are nearby? What movement or pressure feels comfortable? What does the source actually claim? These questions are more useful than assuming that every sore spot is “stuck fascia.”
