Fascia, the webbing surrounding all the tissue within the body. This webbing can get bound restricting movement and causing pain. Myofascial release, which is a form of massage therapy, removes strictures within this layer enabling reparation of alignment within the body and creating space within the body.
If you're a huge Western medicine person and really not into the mumbo jumbo associated with acupuncture and reiki, myofascial release can be your introduction into the world of alternative healing modalities.
So much more restoring than traditional massage, myofascial release can help you sleep better (back to that creating space in the body for improved lymph flow and improved energy flow), and even if one session doesn't convince you that each one of us is more than matter (we are each such an incredibly complex mixture of matter and energy), you have nothing to lose by trying it out.
