坐马痈属于督脉经，病位在尾骨稍上方，由湿热凝结所致。若局部高起肿胀、迅速溃破且流出稠厚脓液为顺证；若漫无边界、溃破迟缓且流出紫黑色水样液体则为凶险之证。
【注】此病生于尾骨稍上方，归属于督脉经，由湿热凝结而成。局部高肿、溃破快、脓液稠厚的为顺证；若漫肿、溃破迟、流出紫水的为险证。体虚之人患此病，容易形成瘘管。初期适宜用艾炷隔蒜片灸治，以宣通结滞，使疮疡易于溃破和收敛。内服药物与鹳口疽相同。溃破后，内外治疗均参照痈疽溃疡门的方法。
臀痈证属膀胱经，表现为坚硬、闷胀肿胀，由湿热凝结所致。生于臀部肌肉丰厚之处则溃破和收敛迟缓，最理想的状态是红肿高起、色泽红活且疼痛明显。

Zuoma Yong (Abscess at the Sitting-Horse Position) belongs to the Du Meridian. The pathology involves damp-heat coagulation slightly above the sacrococcygeal region. A high, swollen appearance with rapid ulceration and thick pus indicates a favorable prognosis; whereas a diffuse swelling with delayed ulceration and discharge of purple fluid indicates an ominous prognosis.
[Note] This condition arises slightly above the coccyx, belonging to the Du Meridian, caused by the coagulation of damp-heat. High swelling, rapid ulceration, and thick pus are signs of a favorable course; diffuse swelling, delayed ulceration, and discharge of purple fluid are dangerous signs. In patients with deficiency constitution, this condition easily progresses to fistula formation. Initially, moxibustion with garlic slices is appropriate to promote circulation and resolve stagnation, facilitating ulceration and healing. Internal medication should follow the protocol for Guankou Ju (Abscess at the Bird's Beak). After ulceration, internal and external treatments should refer to the section on Ulcerated Carbuncles and Sores.
Tun Yong (Gluteal Abscess) belongs to the Bladder Meridian. It presents as hard, stifling swelling due to damp-heat coagulation. When located in areas of thick muscle, ulceration and healing are slow. The most desirable presentation is high swelling, bright redness, and pain.
[Note] This condition is caused by damp-heat coagulation in the Bladder Meridian. Arising in the fleshy part of the buttocks, swelling, ulceration, and healing are all slow. Initially, moxibustion with garlic slices is recommended, along with administration of Xianfang Huoming Yin (Immortal Life Elixir Decoction) to dissipate the swelling; if ineffective, Tou Nong San (Pus-Penetrating Powder) should be taken, followed by incision when pus is ripe. After ulceration, internal and external treatments follow the protocols for Ulcerated Carbuncles and Sores.
Shangma Yong (Upper Horse Abscess) and Xiama Yong (Lower Horse Abscess) arise in the creases on the left and right sides, respectively. They are caused by damp-heat in the Bladder Meridian combined with emotional distress such as worry and indignation. Black depression indicates severe disease, while high swelling indicates mild disease.
[Note] This condition arises in the gluteal fold, involving damp-heat in the Bladder Meridian and qi stagnation due to emotional imbalance like worry and anger. Initially presenting like millet grains, it gradually develops into painful nodules accompanied by alternating chills and fever. High swelling and bright redness indicate a mild case; flat depression and black hardness indicate a severe case. Initially, Jingfang Baidu San (Schizonepeta and Saposhnikovia Powder to Rescue from Toxicity) is administered to relieve chills and fever, followed by Neituo Qianghuo Tang (Internal Supportive Decoction with Notopterygium). As pus formation approaches completion, Tuoli Tou Nong Tang (Decoction for Internal Support and Pus Penetration) is given. All other internal and external treatments follow the protocols for Ulcerated Carbuncles and Sores.
