股阴疽发大股中，阴囊之侧坚肿疼，七情不和忧愤致，溃后缠绵功难成。
【注】此证一名赤施，发生于股内合逢下近阴囊之侧，因偏在厥阴经，故名大股也。坚
硬漫肿木痛，由七情不和，忧思愤郁，凝结而成。因在阴经，起长、溃脓，俱属迟缓，溃
后尤见缠绵，收敛成功者甚少。初起与附骨疽治法同，肿溃俱按痈疽肿疡、溃疡门。

伏兔穴处忌生疽，肿硬针灸不相宜，疼痛彻心寒热作，胃火毒滞溃难医。
【注】经云∶伏兔不宜生疮。盖伏兔乃胃经穴道，在膝盖之上六寸正中，用力大如掌，
一堆高肉处，禁用针灸。始发，寒热交作，疼痛彻心，由胃火毒滞而成。溃后最难收敛。初
治同附骨疽，溃按溃疡门。

股阴疽发生在两大腿中间，阴囊旁边出现坚硬肿胀疼痛，多由七情不和、忧愁愤懑所致，溃破后病程缠绵难愈，难以收功。
【注】此证又名赤施，发生于大腿内侧合缝穴下方靠近阴囊的一侧，因为偏在厥阴经（足厥阴肝经），所以称为大股疽。患处坚硬漫肿且麻木疼痛，是由于七情不调，忧思愤郁，导致气血凝结而成。因为病变位于阴经，起病缓慢，化脓迟缓，溃破后尤其表现为缠绵难愈，能收敛愈合的很少。初起时的治法与附骨疽相同，肿胀期和溃破期分别参照痈疽肿疡门和溃疡门的记载处理。
横疽生于左侧，阴疽生于右侧，大腿内侧合缝折纹处肿胀坚硬疼痛，疼痛牵引至睾丸，形状像蛤蟆，这是由于三阴经（足太阴脾经、足少阴肾经、足厥阴肝经）气机郁滞凝结所致。
【注】这两种证候都发生在大腿内侧合缝折纹之间，左边叫横疽，右边叫阴疽，归属于三阴经，由七情郁滞凝结而成。患处漫肿坚硬，时常疼痛，严重时疼痛牵引睾丸，向上波及少腹，形状长如蛤蟆，一到两个月才能溃破，由此可知脓液位置很深，破溃后若脓液稠厚可以痊愈，若是败浆样脓液则最难敛口，日久必然形成瘘管。初期治疗同附骨疽，溃破后参照痈疽溃疡门处理。如果脓水淋漓不尽，日久可能生出虫子，形状类似蛔虫，这也是脓液深部郁积日久所化生的，属于逆证。
伏兔穴部位忌讳生疽，此处肿胀坚硬不宜进行针灸治疗，疼痛剧烈直达内心，伴有寒热发作，因胃火毒邪滞留，溃破后难以医治。
【注】医经中说：伏兔穴不宜生疮。因为伏兔是胃经的穴位，位于膝盖上方六寸正中，用力按压时感觉大如手掌，是一堆隆起的肌肉处，禁用针灸。发病初期，寒热交替发作，疼痛彻心，是由胃火毒邪滞留所致。溃破后最难收敛愈合。初期治疗同附骨疽，溃破后参照溃疡门处理。
Guyin Ju (Abscess of the Inner Thigh) occurs in the center of the large thigh, presenting with hard swelling and pain on the side of the scrotum. It is caused by disharmony of the Seven Emotions (Joy, Anger, Worry, Pensiveness, Sorrow, Fear, Fright), specifically grief and indignation. After ulceration, the condition lingers and is difficult to heal.
[Note] This syndrome is also known as Chishi (Red Spread). It occurs on the side of the inner thigh near the scrotum, below the Hefeng acupoint. Because it lies predominantly in the Jueyin Meridian (Liver Meridian of Foot-Jueyin), it is called Dagu Ju (Large Thigh Abscess). The area is hard, diffusely swollen, numb, and painful. It results from the condensation of Qi and Blood due to emotional imbalance, including worry, thought, anger, and depression. Since the lesion is in a Yin Meridian, its onset is slow, suppuration is delayed, and after ulceration, it tends to linger; few cases achieve complete healing. The initial treatment is the same as that for Fugu Ju (Abscess adhering to bone). For swelling and ulceration stages, refer to the sections on Swelling Ulcers and Ulcerated Ulcers in the Treatise on Carbuncles and Sores.
Heng Ju (Transverse Abscess) occurs on the left, and Yin Ju (Yin Abscess) occurs on the right. There is hard swelling and pain in the crease of the inner thigh. Pain radiates to the testicles, and the shape resembles a clam. This is caused by stagnation and condensation in the Three Yin Meridians (Spleen, Kidney, Liver) due to emotional depression.
[Note] Both syndromes occur in the creases of the inner thigh. The left is called Heng Ju, and the right is called Yin Ju. They belong to the Three Yin Meridians and result from condensation due to emotional stagnation. The area is diffusely swollen and hard, with intermittent pain. In severe cases, pain radiates to the testicles and extends upward to the lower abdomen. The shape is long like a clam. It takes one to two months to ulcerate, indicating deep pus. If the pus is thick upon rupture, recovery is possible; however, if it is thin and foul (败浆), healing is extremely difficult, often leading to fistula formation over time. Initial treatment is the same as for Fugu Ju. Post-ulceration management follows the section on Ulcerated Ulcers. If pus drains continuously for a long time, worms may appear, resembling roundworms. This is transformed from long-standing stagnation of deep pus and is considered a adverse sign (Ni Zheng).
Ju at the Futu Acupoint is contraindicated. Hard swelling here makes acupuncture and moxibustion unsuitable. Pain is severe enough to penetrate the heart, accompanied by alternating chills and fever. It is caused by stagnation of Stomach Fire and toxic pathogens, making post-ulceration treatment difficult.
[Note] The classics state: "Sores should not arise at Futu." Futu is an acupoint of the Stomach Meridian, located 6 cun directly above the knee cap, where the muscle mass is large and palm-sized when tensed. Acupuncture and moxibustion are strictly prohibited here. Initially, there are alternating chills and fever, and pain penetrating the heart, caused by the stagnation of Stomach Fire and toxins. Healing after ulceration is the most difficult. Initial treatment is the same as for Fugu Ju. Post-ulceration management follows the section on Ulcerated Ulcers.
