成即死。故凡腹中有一定痛处，恶寒倦卧，不能食者，皆当番察，防成内痈。幸毋因循，以至久而脓溃，自伤
其生也。（徐灵胎）
咳即胸中隐痛，心胸甲错，振寒脉数，咽干不渴，时出浊唾腥臭，吐脓如米粥者，肺痈也。少腹重，按之
痛，便数似淋，汗出恶寒，身皮甲错，腹皮绷急如肿状，脉滑数者，肠痈也。胃脘隐痛，手不可近，胃脉沉细，
人迎逆而盛者，胃脘痈也。（《证治准绳》）
脓成则死。所以凡是腹中有固定位置的疼痛，伴有怕冷、疲倦嗜卧、不能进食的情况，都应当仔细审查，防止发展成内痈。千万不要因为拖延，以至于日久化脓溃破，从而伤害自己的生命。（徐灵胎）
咳嗽时胸中隐隐作痛，心胸皮肤粗糙如鳞甲交错，恶寒战栗，脉象数，咽喉干燥但不想喝水，时常吐出浑浊且带有腥臭味的唾沫，吐出像米粥一样的脓液，这是肺痈。小腹部沉重，按压时疼痛，小便频数类似淋证，出汗怕冷，身体皮肤粗糙如鳞甲交错，腹部皮肤紧绷急迫像肿胀的样子，脉象滑数的，是肠痈。胃脘部隐隐作痛，手不能靠近（拒按），胃脉沉细，人迎脉逆乱而盛大的，是胃脘痈。（《证治准绳》）
Once the abscess forms, death ensues. Therefore, in cases where there is a fixed site of pain in the abdomen, accompanied by aversion to cold, fatigue with a desire to lie down, and inability to eat, careful examination is required to prevent the development of internal abscesses (Nei Yong). Do not allow procrastination, which may lead to long-standing suppuration and rupture, thereby harming one's own life. (Xu Lingtai)
Coughing with dull pain in the chest, roughness of the skin over the chest and heart area resembling fish scales (Jin Cuo), chills and tremors, rapid pulse (Mai Shu), dry throat without thirst, frequent expectoration of turbid saliva with a foul or fishy odor, and expectoration of pus resembling congee are characteristics of Lung Abscess (Fei Yong). Heaviness in the lower abdomen, tenderness upon pressure, frequent urination resembling stranguria (Lin Zheng), sweating with aversion to cold, roughness of the body skin resembling fish scales (Shen Pi Jin Cuo), abdominal wall tension and tightness as if swollen, and a slippery and rapid pulse (Mai Hua Shu) indicate Intestinal Abscess (Chang Yong). Dull pain in the epigastrium, intolerance to touch (Ju An), a deep and fine stomach pulse (Wei Mai Chen Xi), and an inverted and excessive Renying pulse (Renying Ni Er Sheng) indicate Gastric Abscess (Wei Wan Yong).
