The causes of lumbago are various. The lumbago dis-cussed in the following is mainly caused by chronic sprain of the lumbar muscles and protrusion of lumbar interver-tebral disc. Lumbago can be caused by damage of the lum-bar muscles, adhesion of muscles and ligaments or joints; or by retrograde pathological changes of the spinal verte-brae complicated by lumbar impairment, rupture of the fibrous ring of the lumbar vertebrae and protrusion of pulpiform nucleus that press on the nerves, periost and ligaments. TCM holds that lumbago is mainly caused by retention of pathological wind, cold and dampness in the meridians; or by malnutrition of the meridians and ten-dons due to kidney asthenia; or by inhibited flow of qi and blood in the meridians due to overstrain and impairment.
