夫腰痛，虽属肾虚，亦涉三因所致。在外则脏腑经络受邪，在内则忧思恐怒，以至房劳
坠堕，皆能致之。方书五种之说，未为详论，但去圣逾远，文籍简脱，难以讨论，虽是缺文
，不可弃置，随其有无，提其纲目，庶几后学以类推寻，为治疗之典据耳。
太阳腰痛，引项脊尻背如重状；阳明腰痛，不可以顾，顾则如有所见，善悲；少阳腰痛
，如针刺其皮，循循然，不可俯仰，不可以顾；太阴腰痛，烦热，腰下如有横木居其中，甚
则遗溲；少阴腰痛，痛引脊内；厥阴腰痛，腰中强急，如张弩弦状。此举六经以为外因治备
。大抵太阳少阴多中寒，少阳厥阴多中风热，太阴阳明多燥湿。以类推之，当随脉别，其如
经中有解脉、散脉，同阴会、阴阳维、衡络、直阳、飞阳、肉里、尻交等穴，皆不出
六经流注，但别行，各有所主，不欲繁引，请寻《内经·刺腰痛论》以备明之，准此，从所

Lumbago, although belonging to Kidney deficiency, is also caused by the Three Causes. Externally, it involves pathogenic invasion of the Zang-Fu organs and meridians; internally, it involves sorrow, worry, fear, and anger, as well as sexual exhaustion or falls, all of which can cause lumbago. The five types of lumbago described in medical texts have not been discussed in detail. As time has passed since the Sages, literature has become sparse and difficult to discuss. Although there are missing texts, they should not be discarded. By extracting their outlines based on availability, future students may infer and seek them out, serving as a canonical basis for treatment.
Taiyang lumbago pulls the neck, spine, buttocks, and back, feeling heavy; Yangming lumbago prevents looking back; when looking back, one sees hallucinations and feels prone to sadness; Shaoyang lumbago feels like needle pricks in the skin, continuous and unrelenting, preventing bending and stretching or looking back; Taiyin lumbago involves irritability and heat, with a sensation of a horizontal blockage below the waist, and severe cases involve urinary incontinence; Shaoyin lumbago pain radiates into the interior of the spine; Jueyin lumbago involves stiffness and tension in the waist, resembling a drawn bowstring. This lists the Six Channels as preparations for treating external causes. Generally, Taiyang and Shaoyin channels often suffer from Cold pathogens, Shaoyang and Jueyin channels often suffer from Wind-Heat pathogens, while Taiyin and Yangming channels often suffer from Dryness-Dampness pathogens. Inferring from this, differentiation should follow the pulse. If there are Jie Mai (Resolving Pulse), San Mai (Scattered Pulse), and acupoints such as Tongyinhui, Yin-Yang Wei, Hengluo, Zhiyang, Feiyang, Roulai, and Kaojiao, these do not belong to the flow and distribution of the Six Channels but are separate pathways with specific dominions. To avoid excessive citation, please consult "Stimulating Lumbago Discussion" in Neijing for clarification. Based on this, treatment should be administered via sweating or purging methods according to the cause.
