Gentle, slow unwinding of Fascia while also opening up any restrictions in the movement of cerebral spinal fluid, are the goals of a Craniosacral Therapy session. I often find that if a muscle is not letting go with traditional Massage Therapy, that a gentle Craniosacral hold to the area will do the trick. Sometimes muscles require a lighter touch to respond.
Chronic pain (especially in the low back, shoulders and neck), limited range of movement and flexibility, pain from old injuries or surgical sites, anxiety from recent and/or long ago traumatic events... all of these point to an unfitness in your Fascia. Holistic therapies can help!
It always makes me smile a little when I'm a few movements into a Massage Therapy session and I hear "You can go deeper" from the client, face down on the table. Yes, I can go deeper, but are your muscles at a point where they are ready for that? Is your Fascia ready?
