凡是腰部及下肢沉重疼痛的，针刺委中穴使其出血，即使是长期顽固的皮疹也能立刻痊愈。其次，主治腰以下至足部麻木不仁（出自《千金方》）。
腰部及下肢感觉像浸在冷水中（参见疝病章节）。承山穴，治疗腰背疼痛、脚部沉重、战栗不能站立、香港脚（脚气病）、膝下肿胀。申脉穴，治疗腰痛导致身体无法抬起、足部寒冷、不能久立、坐卧时感觉像在舟车中颠簸不定。昆仑穴，治疗腰尻部疼痛（《千金方》作踵部疼痛）、足部拘急、脚不能着地。昆仑穴下方，治疗腰痛、偏风半身不遂、脚部沉重疼痛不能着地（出自《明堂经》）。膀胱俞穴，治疗腰足麻木不仁（参见脊部病症）。仆参穴，治疗腰痛无法起身。承山穴，治疗脚部沉重痿软（出自《下经》）。地机穴，治疗腰痛无法俯仰、足部痹痛、屈伸困难。风市穴，治疗冷痹、小腿麻木、腿膝酸痛、腰尻沉重、起坐困难。承山穴，治疗脚部酸痛、不能久立、腰膝沉重、起坐困难、筋脉挛急、无法屈伸。张仲文治疗腰部沉重疼痛、无法转动、起坐困难，以及冷痹导致的脚筋挛急、无法屈伸。灸曲池穴两侧、头左右、脚四处，每处各灸三壮。每次灸一只脚，两火同时点燃，烧灼刚接触到皮肤时，起初感到疼痛，便用两个人从两边同时吹气，直到艾火熄灭。如果在午时施灸，到黄昏时分，患者自行活动脏腑一两回，或者感觉脏腑转动发出雷声，立刻痊愈，效果神奇。上廉穴，治疗腰腿手足麻木不仁（参见偏风章节）。阳辅穴，治疗腰部酸软如坐在水中、膝下皮肤肿胀筋脉挛急、各个关节都疼痛且位置不固定、腋下肿、马刀瘘、喉痹、膝部酸痛、风痹麻木不仁。阴交穴，治疗腰膝拘挛（参见疝病章节）。
仁寿宫备身患有脚疾，奉皇帝诏令针刺环跳、阳陵泉、巨虚下廉、阳辅穴，随即就能行走。大理寺卿赵卿患中风，肢体不能随意运动，不能跪起，针刺上廉、环跳、阳陵泉、巨虚下廉各二穴，随即能够跪起。此法治疗冷痹引起的小腿膝盖疼痛、腰足挛急、足部冷气上冲、不能久立、手足沉重、日渐消瘦，这叫做复连病，适宜灸悬钟穴（即绝骨穴），灸一次即可痊愈（参见《千金方》身湿痹章节）。
《千金翼方》中的温肾汤，主治腰脊膝盖脚部浮肿且肢体不遂（茯苓、干姜、泽泻各二两，桂心三两切碎，每次服用四五钱重，加水二盏，煎至八分盏服用，每日二三次服用）。由此可见，腰脚等疾病，也应当服药，不能专门依赖灸法。
Whenever there is heaviness and pain in the lower back and legs, puncture Weizhong (BL40) to induce bleeding; even long-standing stubborn skin eruptions will be cured immediately. Secondly, it governs numbness from the lower waist down to the feet (as cited in *Qianjin Fang*).
A sensation of cold water on the lower back and legs (see section on Hernia). Chengshan (BL57) treats lower back and back pain, heavy feet, trembling inability to stand, Hongjiao (foot qi disease), and swelling below the knees. Shenmai (BL62) treats lower back pain preventing the body from rising, cold feet, inability to stand for long periods, and a sensation of rocking as if in a boat or carriage during sitting or lying. Kunlun (BL60) treats pain in the lower back and buttocks (*Qianjin* refers to heel pain), foot contracture, and inability to place the foot on the ground. Below Kunlun, it treats lower back pain, hemiplegia due to wind-stroke, heavy painful feet unable to touch the ground (from *Mingtang Jing*). Bladder Shu (BL28) treats numbness of the lower back and feet (see section on spine disorders). Pucan (BL61) treats lower back pain preventing the body from rising. Chengshan (BL57) treats heavy and flaccid feet (from *Xia Jing*). Diji (SP8) treats lower back pain preventing flexion and extension, bi-syndrome pain in the feet, and difficulty in bending and straightening. Fengshi (GB31) treats cold bi-syndrome, numbness in the calves, soreness and pain in the legs and knees, heaviness in the lower back and buttocks, and difficulty in rising and sitting. Chengshan (BL57) treats sore and painful feet, inability to stand for long periods, heaviness in the lower back and knees, difficulty in rising and sitting, tendon cramps, and inability to bend and straighten. Zhang Zhongwen treats heavy and painful lower back, inability to turn, difficulty in rising and sitting, and cold bi-syndrome causing leg tendon cramps and inability to bend and straighten. Moxibustion at Quchi (LI11) on both sides, the head left and right, and four points on the feet, three moxa cones at each point. When moxibusting one foot, apply two fire sources simultaneously; when the heat just reaches the flesh, initially feeling pain, have two people blow from both sides until the fire extinguishes. If moxibustion is performed at noon, by dusk, the patient moves their internal organs once or twice voluntarily, or feels the internal organs rotating with a sound like thunder, leading to immediate cure; this is miraculous. Shanglian (LI13) treats numbness of the lower back, legs, hands, and feet (see section on Wind-Stroke). Yangfu (GB38) treats a soft lower back as if sitting in water, swelling of the skin below the knees with tendon cramps, pain in all joints without fixed location, axillary swelling, scrofula (Ma Dao), throat obstruction, knee soreness, and wind-bi numbness. Yinjiao (RN7) treats lower back and knee contracture (see section on Hernia).
Beishen of Renshou Palace suffered from a foot ailment and, by imperial decree, was needled at Huantiao (GB30), Yanglingquan (GB34), Zusanli (ST36 - specifically Xiaguan/Juxia Lian), and Yangfu (GB38); she could walk immediately. Zhao Qing, Minister of Justice, suffered from wind-stroke with limb immobility and inability to kneel or rise; he was needled at Shanglian (LI13), Huantiao (GB30), Yanglingquan (GB34), and Zusanli (ST36 - specifically Xiaguan/Juxia Lian), two points each, and could immediately kneel and rise. This method treats cold bi-syndrome causing calf and knee pain, lower back and foot contracture, upward rushing of cold qi from the feet, inability to stand for long periods, heaviness in hands and feet, and daily emaciation; this is called Fuliann Bing, and it is suitable to moxa Xuanzhong (Guanyuan/Abegut). One application of moxa leads to cure (see *Qianjin Fang* section on Body Wet Bi-Syndrome).
*Qianjin Yi Fang*'s Wushen Tang primarily treats edema and immobility of the lower back, spine, knees, and feet (Poria, Dried Ginger, Alisma each 2 liang, Cinnamon Twig 3 liang, chopped; take 4-5 qian weight per dose, add 2 zhan of water, decoct to 0.8 zhan, take orally, 2-3 times daily). Thus, diseases of the lower back and legs should also involve herbal medicine and cannot rely solely on moxibustion.
