有一患者，瘀血失砭，胀痛烦渴，纵饮凉童便，渴胀顿止，以萝卜细捣涂之，瘀血
渐散，已而患处作痒，仍涂之。痒止后，口干作渴，小腹引阴茎作痛，小便如淋，时出
白津，此肝经郁火也，遂以小柴胡汤，加大黄、黄连、山栀饮之，诸证悉退；再用养血
等药而安。夫小腹引阴茎作痛等证，往往误认为寒证，投以热剂，则诸窍出血，或二便
不通，以及危殆，轻亦损其目矣。
营卫之气滞也，用复元通气散。筋骨作痛，肝肾之气伤也，用六味地黄丸。内伤下
血作痛，脾胃之气虚也，用补中益气汤。外伤出血作痛，脾肺之气虚也，用八珍汤。大
凡下血不止，脾胃之气脱也。吐泻不食，脾胃之气败也，苟预为调补脾胃，则无此患矣。
若痛至四五日不减，或至一二日方痛，欲作脓也，用托里散。若以指按下复起，脓已
成也，刺去其脓，痛自止。若头痛时作时止，气血虚也，痛而兼眩属痰也，当生肝血，补
脾气。 有一患者，患处胀痛，悲哀忿怒，此厥阳之火，为七情激之而然耳，遂砭去瘀血，
以小柴胡汤，加山栀、黄连、桔梗而安；后用生肝血，养脾气之药，疮溃而敛。 戴给
事坠马，腿肿痛而色黯，食少倦怠，此元气虚弱，不能运散瘀血而然耳，遂用补中益气，
去升麻、柴胡，加木瓜、茯苓、芍药、白术，治之而痊。 儒者王清之，跌腰作痛，用定
痛等药不愈，气血日衰，面耳黧色。薛曰∶腰为肾之府，虽曰闪伤，实肾经虚弱所致，遂
用杜仲、补骨脂、五味、山茱、苁蓉、山药空心服；又以六君、当归、白术、神曲各二
钱，食远服，不月而瘥。 一三岁儿，闪腰作痛，服流气等药，半载不愈。薛曰∶此禀
肾气不足，不治之症也，后果殁。
有一位患者，因瘀血未能通过砭石疗法排出，出现胀痛、心烦口渴的症状。他大量饮用凉的童便（儿童尿液），口渴和腹胀随即停止。随后用萝卜细细捣碎外敷患处，瘀血逐渐消散。不久后患处感到瘙痒，继续外敷萝卜泥。瘙痒停止后，出现口干口渴、小腹牵引阴茎疼痛、小便像淋证一样涩痛、时常流出白色津液的情况。这是肝经郁火所致，于是用小柴胡汤，加入大黄、黄连、山栀（栀子）让他服用，所有症状全部消退；之后再用养血等药物调理而痊愈。像小腹牵引阴茎疼痛这类证候，往往被误认为是寒证，如果投以热性药剂，会导致各种窍道出血，或者大小便不通，甚至危及生命，轻则损伤眼睛。
营卫之气运行滞涩，使用复元通气散。筋骨作痛，是肝肾之气受损，使用六味地黄丸。内伤导致下血并伴有疼痛，是脾胃之气虚弱，使用补中益气汤。外伤导致出血并伴有疼痛，是脾肺之气虚弱，使用八珍汤。大凡下血不止，是脾胃之气脱失的表现。呕吐腹泻且不能进食，是脾胃之气败坏的表现，如果预先调补脾胃，就不会有这种祸患了。
如果疼痛持续四五天不减轻，或者过了一两天才开始疼痛，这是将要化脓的表现，使用托里散。如果用手指按压患处，松开后凹陷立即恢复，说明脓已经形成，刺破排去脓液，疼痛自然停止。如果头痛时作时止，是气血虚弱的表现；疼痛兼有眩晕属于痰湿，应当滋养肝血，补益脾气。
有一位患者，患处胀痛，情绪悲哀愤怒，这是厥阳之火，被七情（喜、怒、忧、思、悲、恐、惊）激发所致。于是用砭石去除瘀血，服用小柴胡汤，加入山栀、黄连、桔梗而安定病情；之后再用滋养肝血、补益脾气的药物，疮口溃破后愈合。戴给事从马上摔落，腿部肿痛且颜色发暗，饮食减少且倦怠乏力，这是元气虚弱，不能运化消散瘀血所致。于是使用补中益气汤，去掉升麻、柴胡，加入木瓜、茯苓、芍药、白术，治疗而痊愈。儒者王清之，腰部扭伤作痛，服用定痛等药物无效，气血日渐衰弱，面色和耳部呈现黧黑之色。薛己说：腰是肾的府邸，虽然说是闪挫损伤，实际上是肾经虚弱所致。于是让他空腹服用杜仲、补骨脂、五味子、山茱萸、肉苁蓉、山药；又以人参、白术、茯苓、甘草（六君子汤成分）、当归、神曲各二钱，在饭后服用，不到一个月就康复了。一个三岁的孩子，闪腰作痛，服用流气等药物，半年未愈。薛己说：这是禀受肾气不足，是不治之症，后来果然去世了。
A patient suffered from distending pain, vexation, and thirst because blood stasis had not been expelled by scarification. He drank large amounts of cold urine from a young boy (Tongbian), after which the thirst and abdominal distension ceased immediately. The bruised area was then covered with finely mashed radish, causing the blood stasis to gradually dissipate. Subsequently, the affected area became itchy, so the radish paste continued to be applied. After the itching stopped, he developed dry mouth and thirst, pain in the lower abdomen radiating to the penis, urinary symptoms resembling strangury (Lin syndrome), and occasional discharge of white fluid. This was diagnosed as constrained fire in the Liver channel. Xiao Chai Hu Tang (Minor Bupleurum Decoction) was administered with added Dahuang (Rhubarb Rhizome), Huanglian (Coptis Rhizome), and Shanzhi (Gardenia Fruit). All symptoms subsided; subsequently, blood-nourishing herbs were used to restore health. Conditions such as lower abdominal pain radiating to the penis are often misdiagnosed as Cold syndromes. Administering hot-natured agents in such cases can cause bleeding from various orifices, obstruction of urination and defecation, critical danger, or even damage to the eyes.
Stagnation of Ying and Wei Qi (Nutritive and Defensive Qi) is treated with Fuyuan Tongqi San (Revitalizing Circulation and Promoting Qi Powder). Pain in sinews and bones indicates injury to the Qi of the Liver and Kidneys, treated with Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill). Internal injury with hematochezia accompanied by pain indicates deficiency of Spleen and Stomach Qi, treated with Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). External trauma with bleeding and pain indicates deficiency of Lung and Spleen Qi, treated with Bazhen Tang (Eight-Treasure Decoction). Generally, persistent hematochezia indicates the collapse of Spleen and Stomach Qi. Vomiting, diarrhea, and inability to eat indicate the failure of Spleen and Stomach Qi. If the Spleen and Stomach were tonified and regulated in advance, this disaster would have been avoided.
If pain persists for four to five days without relief, or begins only after one or two days, it indicates impending suppuration (pus formation); Tuoli San (Support the Interior Powder) should be used. If pressing the area with a finger leaves an indentation that rebounds immediately, pus has formed; puncturing and draining the pus will stop the pain. Occasional headaches indicate Qi and Blood deficiency. Pain accompanied by dizziness suggests Phlegm; treatment should focus on generating Liver Blood and tonifying Spleen Qi.
Another patient presented with distending pain at the lesion site, sorrow, and anger. This was caused by Jueyang Fire (Hyperactive Yang Fire) stimulated by the Seven Emotions (Seven Affects). Scarification was performed to remove blood stasis, followed by Xiao Chai Hu Tang (Minor Bupleurum Decoction) with added Shanzhi (Gardenia Fruit), Huanglian (Coptis Rhizome), and Jiegeng (Platycodon Root). The condition stabilized. Subsequently, herbs to nourish Liver Blood and tonify Spleen Qi were used, leading to the ulceration and healing of the sore. Dai Jishi (Censor Dai) fell from a horse, resulting in swollen and painful legs with dark discoloration, poor appetite, and fatigue. This was due to weak Yuan Qi (Primary Qi) failing to transform and disperse blood stasis. Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) was prescribed, with Shengma (Cimicifuga Rhizome) and Chaihu (Bupleurum Root) removed, and Mugua (Chaenomeles Fruit), Fuling (Poria), Shaoyao (Peony Root), and Baizhu (Atractylodes Macrocephala Rhizome) added. He recovered. Wang Qingzhi, a scholar, suffered from lumbar strain pain. Treatment with Dingtong (Stop Pain) herbs failed; his Qi and Blood declined daily, and his face and ears turned dark. Xue Ji stated: "The waist is the mansion of the Kidney. Although this is a sprain injury, it is actually caused by weakness of the Kidney channel." He prescribed Duzhong (Eucommia Bark), Buguzhi (Psoralea Fruit), Wuweizi (Schisandra Fruit), Shanzhuyu (Cornus Fruit), Rongrong (Cistanche Stem), and Shanyao (Dioscorea Rhizome) taken on an empty stomach. Additionally, Liujunzi Tang (Six-Gentlemen Decoction) components—Ren Shen (Ginseng Root), Baizhu (Atractylodes Macrocephala Rhizome), Fuling (Poria), Gancao (Licorice Root)—along with Danggui (Angelica Sinensis Root) and Shenqu (Medicated Leaven), each 2 qian, were taken after meals. He recovered within a month. A three-year-old child suffered from lumbar strain pain. Treatment with Liuqi (Moving Qi) herbs for half a year yielded no results. Xue Ji stated: "This is due to insufficient congenital Kidney Qi; it is an incurable case." The child indeed died later.
