[General Principle] The lower back is the external orifice of the Kidney and is suitable for warming and tonifying treatments; stagnation of dampness and blood stasis both cause pain. There are also cases where pain radiates to the shoulders and back, which belong to diseases of the Taiyang (Greater Yang) meridian, requiring investigation into their root causes.
A sensation of heaviness and pain in the waist, as if carrying five thousand coins around the waist, indicates cold-dampness invading the Kidney meridian. It is appropriate to use the Shenzhuo Decoction (Kidney-Attaching Decoction) from contemporary formulas.

There is no other method to dispel cold and promote diuresis; do not say that contemporary formulas lack efficacy.
(Ber An's Note: The original annotation in *San Yin Fang* states "If there is diarrhea, add Cangzhu, Chenpi, and Dingxiang".)
Lumbar pain that is unbearable, feeling like being pierced by knives or awls, indicates blood stasis accumulating at the waist. It is appropriate to use Lujiao Liyao Decoction (Deer-Horn Lumbar-Benefiting Decoction).

Combine Lujiao, Honghua with Xuduan, then add Niuxi and boil into a paste.

Shanyao, Yunling, and Zexie are added, while Dihuang nourishes and gradually brings comfort.
(Ber An's Note: One may eat pork kidneys boiled with aged wine, or adding Duzhong and Xuduan is also good. Another method uses four liang of Walnut Meat and one liang of Buguzhi pounded together, taken three to four qian daily.)
Lumbar pain radiating to the back, or combined with chills, fever, and headache, indicates Wind-Cold attacking the Taiyang meridian. It is appropriate to use Renshen Baidu San (Ginseng Detoxification Powder).
