The purpose of this study was to examine the possible origins of non-specific or atraumatic back pain by applying the Gate Theory of pain and current physiologic concepts. I present a theory that accounts for the initiation and potential consequences of neuromusculoskeletal pain incorporating failure of the mechanism of muscle relaxation and resulting in pain and compromise of the lymphatic system. The theory provides an alternative to current theories and hypotheses of the cause and consequences of neuromusculoskeletal pain.
