Have you ever had a client whose injury seemed to cause problems long after the site had healed? That is not as unusual as one might think. Research I conducted in the late 1970s with a biophysicist named Dr. Zvi Karni led us to discover that the body can retain the imprints of physical trauma in the tissues. These imprints, which can also include intense feelings that occurred at the time of injury, actually leave a residue embedded in the body. I call these areas of restricted or disorganized energy "energy cysts."
