5 pairs of lumbar nerves supply the skin on the lower abdomen, thighs, and fronts of the legs. The lumbar spine is more commonly referred to as the lower back. This region begins roughly five or six inches below the shoulder blades, connecting with the thoracic spine at the top and extending downward to the sacral spine.
Treatments addressing this region can be highly effective in reducing lower back pain. Muscles in the lumbar region may become tense from repeated use or injury. With the services of an experienced massage therapist, much of that tension can be released.
