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》）
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).
