陈实功曰∶咬骨疽，发在大腿内股，不肿不红，痛彻骨髓，初宜雷火针针之，内
用万灵丹以酒调服之。（《正宗》）
汪省之曰∶箕门痈生于股内近膝，乃足太阴脾经湿毒所生。（《理例》）
又曰∶骨毒滞疮，又名腿发。乃足太阴脾经，生于腿上箕门穴。如痛可治；不
痛难治。十二日可刺，如脓黄赤色可治；青稀腐臭者不治。其疮赤白色，是骨毒瓦斯发于外，十日内未脓，必死。

申斗垣曰∶肉蜈蜂生大腿外面，皮肤不觉红肿，内里疼痛难忍。治斯证者，切
不可轻用刀刺，若误犯之，毒瓦斯直透心胸，疼痛不止，多致不救。治当用白降丹掺膏
药上贴，三日后取下，败肉如蜂之状，再用生肌等药收功。（《启玄》）
胡公弼曰∶肉蜈蜂所生之处，乃足厥阴肝经部位，风湿郁积，气血阻滞，注久
而成此毒。一犯刀刺，蜂毒直入心胸，母传子受，肆毒无忌，直犯君主，故多不救。（《青囊》）
陈实功曰∶玄疽生于左腿夹缝之下三寸，漫肿连阴，疼及大腿。（《正宗》）
陈实功曰∶阴疽生于右腿夹缝之下三寸，痛连肾子，小腹亦痛。（《正宗》）
《心法》曰∶膝痈生膝盖，色红 肿疼痛，属气血实， 疽亦生在膝盖，肿大如
痈，其色不变，寒热往来，属气血虚，和软为顺，坚硬如石者逆。经云∶肉之小会
为溪，溪者二肘二膝四腕也。凡脾病在溪，肾有邪其气留于两腰，凡筋病皆属于节，筋
乃肝之余，故又属肝，是以溪会有病，皆从脾肾肝三经邪气乘之也，惟两膝俱生，属败证，不可治也。
陈实功说：咬骨疽，发生在大腿内侧股部，局部不肿不红，疼痛深入骨髓。初期适宜用雷火针进行针刺治疗，内服万灵丹并用酒调服。（《外科正宗》）
汪省之说：箕门痈生于大腿内侧靠近膝盖处，是由足太阴脾经的湿毒蕴结所致。（《外科理例》）
他又说：骨毒滞疮，又名“腿发”。病位在足太阴脾经，发生于腿部箕门穴处。如果疼痛尚可治疗；如果不痛则难治。发病十二天可以刺破排脓，如果脓液呈黄赤色则易治；若脓液青稀且腐臭则属不治之症。如果疮面呈赤白色，这是骨毒之气外发的表现，若十日内未能化脓，患者必死。
申斗垣说：肉蜈蜂生在大腿外侧，皮肤不觉红肿，但内部疼痛难以忍受。治疗此证时，切不可轻易用刀刺破，如果误犯刀刺，毒气会直接透入心胸，导致疼痛不止，多数会导致死亡。治疗应当使用白降丹掺在膏药上贴敷，三天后取下，坏死的肌肉呈现如蜂状，然后再用生肌等药物收口治愈。（《外科启玄》）
胡公弼说：肉蜈蜂发生的部位，属于足厥阴肝经的区域，因风湿郁积，气血阻滞，日久便形成此毒。一旦误用刀刺，蜂毒直入心胸，母脏传子脏受邪，肆意肆虐无忌，直接侵犯君主（心），所以多数无法救治。（《青囊秘传》）
陈实功说：玄疽生于左腿两腿之间缝隙下方三寸处，漫肿并牵连阴部，疼痛波及大腿。（《外科正宗》）
陈实功说：阴疽生于右腿两腿之间缝隙下方三寸处，疼痛牵连睾丸（肾子），小腹部也疼痛。（《外科正宗》）
《医宗心法》说：膝痈生于膝盖，表现为色红、肿胀、疼痛，属于气血实证；膝疽也生在膝盖，肿大如同痈，但颜色不变，伴有寒热往来症状，属于气血虚证。疮疡柔软为顺证，坚硬如石者为逆证。经文说：肌肉的小交会之处称为“溪”，所谓的“溪”指的是两肘、两膝和两腕共六个部位。凡是脾病多在“溪”处显现，肾脏有邪气则其气停留于两腰，凡是筋病都归属于节，筋是肝之余气所生，所以又归属于肝。因此，“溪”和“会”处的病变，都是由于脾、肾、肝三经的邪气乘虚侵袭所致。只有当两膝同时发病时，才属于败证，不可治疗。
Chen Shigong stated: "Yao Gu Ju" (Bone-Biting Abscess) occurs in the medial thigh. There is no swelling or redness, but the pain penetrates to the bone marrow. Initially, it is suitable to treat with Lei Huo Zhen (Thunder-Fire Needle), and internally administer Wan Ling Dan (Ten Thousand Spirits Pill) mixed with wine for ingestion. (*Waike Zhengzong*)
Wang Shengzhi stated: "Jimen Yong" (Abscess at Jimen Acupoint) arises near the knee on the medial thigh, caused by damp-toxin accumulation in the Foot-Taiyin Splein Meridian. (*Waike Lili*)
He further stated: "Gu Du Zhi Chuang" (Bone-Toxin Stagnant Ulcer), also known as "Tui Fa" (Leg Eruption). It occurs along the Foot-Taiyin Splein Meridian at the Jimen acupoint on the leg. If painful, it is treatable; if painless, it is difficult to treat. At twelve days post-onset, it may be lanced. If the pus is yellow-red, it is treatable; if the pus is green, thin, and foul-smelling, it is incurable. If the ulcer surface is red-white, this indicates the manifestation of bone-toxin qi externally. If suppuration does not occur within ten days, death is inevitable.
Shen Douyuan stated: "Rou Wu Feng" (Flesh-Winged Bee) arises on the lateral thigh. The skin shows no obvious redness or swelling, but internal pain is unbearable. When treating this condition, one must absolutely avoid using a knife to lance it. If mistakenly lanced, the toxic qi will penetrate directly into the heart and chest, causing unceasing pain, often leading to untreatable outcomes. Treatment should involve applying Bai Jiang Dan (White Reduction Powder) onto a plaster patch. After three days, remove the patch. When necrotic tissue resembles bee wings, use flesh-regenerating medicines to complete the healing. (*Waike Qixuan*)
Hu Gongbi stated: The site where "Rou Wu Feng" arises belongs to the region of the Foot-Jueyin Liver Meridian. It is formed by long-term stagnation of wind-dampness and obstruction of qi and blood. Once lanced with a knife, the bee toxin enters the heart and chest directly. The mother organ transmits the pathogen to the son organ, allowing the toxin to spread recklessly and attack the Monarch (Heart), hence most cases are fatal. (*Qingnang Mibian*)
Chen Shigong stated: "Xuan Ju" (Dark Carbuncle) arises three cun below the crease between the legs on the left side. It presents with diffuse swelling extending to the genitalia, with pain radiating to the thigh. (*Waike Zhengzong*)
Chen Shigong stated: "Yin Ju" (Yin Carbuncle) arises three cun below the crease between the legs on the right side. The pain extends to the testicles, and the lower abdomen is also painful. (*Waike Zhengzong*)
*Yizong Xinfa* stated: "Xi Yong" (Knee Abscess) occurs on the knee, presenting with redness, swelling, and pain, indicating an excess syndrome of qi and blood. "Xi Ju" (Knee Carbuncle) also occurs on the knee, with swelling similar to an abscess but without color change, accompanied by alternating chills and fever, indicating a deficiency syndrome of qi and blood. Softness of the lesion is a favorable sign; hardness like stone is an unfavorable sign. The classic text states: Small intersections of muscle are called "Xi". The "Xi" refers to the two elbows, two knees, and two wrists. Whenever Spleen disease manifests in the "Xi", Kidney pathogens tend to linger in the two loins. All tendon diseases belong to the joints. Since tendons are the surplus of the Liver, they also belong to the Liver. Therefore, diseases in the "Xi" and joint intersections are all caused by pathogenic factors from the Spleen, Kidney, and Liver meridians invading the body. Only when both knees are simultaneously affected is it considered a failing syndrome, which is untreatable.
