Spinal Flush
When I am working on clients, I usually ask them to let me know if I hit sore spots during the Spinal Flush, as it can help me identify what meridians are involved with the issues the person is seeking help for, whether they are physical, emotional or existential.
You can give yourself a spinal flush by tying two tennis balls into a sock, and rolling them down the hollows on either side of the spin, either against a wall or on a floor or mat. This may be quite painful at first, so be kind to yourself!
