Pain in the lower back is caused by coldness of Kidney Water leading to stagnation of Liver Wood. The Kidneys reside in the lumbar region; when Kidney Water is cold, Spleen Earth becomes damp. Dampness of Earth causes stagnation of Liver Wood and sinking of Yang Qi, resulting in pain in the lower back. There are also cases of lower back pain due to excessive sexual indulgence, where Yin Essence is greatly depleted and the root of Yang Qi is damaged. This is the origin of withered Wood and defeated Earth, which gives rise to pain. If the cause is dampness and the pattern is excess, Shen Zhuo Tang (Kidney Fixing Decoction) is the primary formula. If the cause is cold and the pattern is deficiency, Guizhi Jiang Ling Ejiao Tang (Cinnamon Twig, Ginger, Poria, and Donkey-hide Gelatin Decoction) is the primary formula. If caused by external contraction of Wind-Cold, it should be treated according to the methods for Cold Damage diseases, which is not covered in this example.

Headache is caused by the rebellion of Wind, Cold, and Fire Qi upwards. However, there are also cases of headache due to deficiency of Yin Blood and flourishing of Yang Heat. There are also cases due to deficiency of Yang Qi and flourishing of Yin Cold. Headache due to blood deficiency is relatively mild, whereas headache due to Yang deficiency is particularly severe. In cases of True Headache (Zhen Tou Tong), the pain is extremely severe, involving the entire brain, with cold hands and feet extending to the joints; this condition is incurable. If the headache is due to flourishing Fire, Yuanshen Yin (Scrophulariae Radix Infusion) is the primary formula. If due to blood deficiency, Danggui Buxue Tang (Danggui Tonifies the Blood Decoction) added with Lurong (Cervus Nippon Cornu Colla) is the primary formula. If due to Kidney Yin deficiency, Zuogui Yin (Left Restoring Infusion) with modifications is the primary formula. If due to Yang deficiency, Wuzhuyu Tang (Evodiae Fructus Decoction) is the primary formula. If due to external contraction of Wind-Cold, it should be treated according to the methods for Cold Damage diseases, which is not covered in this example.
