p75 of pain is caused by trigger points areas of contracted cells in muscle tissue, but they are drastically under-diagnosed as the source of pain. Trigger points may refer pain and other symptoms both in the local area andor to other areas of the body, but since over 74 of trigger points are emnotem located in the area where you feel pain, treating the local area does not resolve the problem most of the time. The most common referral patterns have been well documented and diagrammed over decades of research.ppThe introductory chapter of this e-book includes general guidelines for self-help techniques and muscle care. Chapter 2 contains a diagram of a body divided into zones, with a list of muscles that may contain trigger points which are referring pain and other symptoms to each zone, so that you will know which subsequent chapters you need to read. The Appendix has extensive information on perpetuating factors that will cause trigger points to form in any of the muscles of the body.
