The importance of fascia
Fascia supports and covers your muscles, and everything else including organs, bones and nerves.  Fascia is interwoven like threads in fabric, connecting every part of the body to every other part.  It binds the human body into an integral whole, allowing the proper function and moving structures including joints, tendons and muscles.
Fascia can become restricted and inelastic from trauma such as accidents and surgery, as well as from poor posture, chronic inflammation and overuse.  Prolonged tension from stress or emotional upset can also cause restrictions.  Restrictions in facia pull on muscles and other structures, causing tightness, pain and limited movement.
