诸浮数脉，应当发热，而反洒淅恶寒，若有痛处，当发其痈。
【注】
诸浮数脉，谓寸、关、尺六脉俱浮数也。浮脉主表，数脉主热，若是表邪，则当发热
而洒淅恶寒也。今非表邪，应当发热，不当恶寒，若有痛处，乃当发痈之诊，非表邪
之诊也。
【集注】
周扬俊曰：病之将发，脉必兆之。夫浮数阳也，热也，浮数兼见，为阳中之阳，是其
热必尽显于外矣。而反洒淅恶寒，证不相应，何哉？必其气血凝滞，荣卫不和，如经
所谓荣气不从，逆于肉理，乃生痈肿，阳气有余，荣气不行，乃发为痈是也，况其身
已有痛处乎。夫脉之见者阳也，其将发而痛者亦属阳，故曰：当发其痈。

师曰：诸痈肿，欲知有脓无脓，以手掩肿上，热者为有脓，不热者为无脓。
【注】
诸痈肿者，谓诸阴阳痈肿也。不论阴阳，凡诸痈肿，欲知有脓无脓，当以手掩之肿上
，热则能腐化成脓。故热者为有脓，不热者为无脓也。
【集注】
周扬俊曰：师之所以教人，知痈已成欲其溃，未成托之起也。

凡是浮数脉，应当出现发热症状，却反而感到怕冷如冷水洒身，如果身体某处有疼痛，应当是痈肿将要发作的征兆。
【注】
所谓的浮数脉，是指寸、关、尺三部六脉都呈现浮数之象。浮脉主表证，数脉主热证，如果是表邪致病，则应当发热并且伴有怕冷如冷水洒身的感觉。现在并非表邪致病，应当发热而不应当恶寒，如果身体某处有疼痛，这是痈肿将要发作的诊断依据，而不是表邪致病的诊断依据。
【集注】
周扬俊说：疾病将要发作时，脉象必定会有预兆。浮数和数脉都属于阳脉，代表热证，浮脉和数脉同时出现，是阳中之阳，说明热势必定完全显露于体表。却反而感到怕冷如冷水洒身，症状与脉象不相符合，为什么呢？一定是气血凝滞，营卫不和，正如经典所说“营气不顺畅，逆乱于肌肉纹理之间，就会发生痈肿；阳气有余，营气运行不畅，就会发为痈”，况且患者身上已经有疼痛之处了。脉象显现的是阳证，即将发作且疼痛的也属于阳证，所以说：应当是痈肿将要发作。

老师说：对于各种痈肿，想要知道是否有脓，用手按压在肿胀部位，感觉热的就是有脓，不热的就是无脓。
【注】
所谓的各种痈肿，是指各种阴阳属性的痈肿。不论阴阳属性，凡是各种痈肿，想要知道是否有脓，应当用手按压在肿胀部位，如果发热则能腐化成脓。所以感觉热的就是有脓，不热的就是无脓。
【集注】
周扬俊说：老师之所以这样教导人，是为了让人知道痈肿已经形成，促使它溃破；尚未形成，促使它托毒外出并起发。

肠痈这种病，患者皮肤粗糙如鳞甲交错，腹部皮肤紧张，按压时柔软像肿胀的样子，但腹部没有积块，身体没有发热，脉象数，这是肠内有痈脓，用薏苡附子败酱散主治。
【注】
痈生于体内，气血被痈邪所夺，不能外达滋养肌肤，所以皮肤枯皱如鳞甲交错。腹部皮肤紧张似肿胀，但按压时软，询问得知腹部没有积块，审察得知身体没有表热，诊察得知脉象数，并没有外在的症状表现。这是肠内有痈脓，主治方剂为薏苡附子败酱散，作用是流通肠胃，消除痈肿。

In cases of floating and rapid pulse (Fushu Mai, 浮数脉), fever should be present, yet the patient instead experiences chills as if cold water is being sprinkled on them. If there is a specific painful area, an abscess (Yong, 痈) is likely to develop.
[Annotation]
"Floating and rapid pulse" refers to the pulse at the Cun, Guan, and Chi positions on both wrists all presenting as floating and rapid. A floating pulse indicates exterior syndrome, while a rapid pulse indicates heat. If caused by exterior pathogenic factors, fever accompanied by chills would be expected. However, this is not an exterior pathogenic condition; fever should occur without chills. The presence of localized pain indicates a diagnosis of impending abscess formation, rather than an exterior pathogenic diagnosis.
[Collected Notes]
Zhou Yangjun stated: When a disease is about to manifest, the pulse will show signs beforehand. Floating and rapid pulses belong to Yang and represent heat. Their simultaneous appearance signifies "Yang within Yang," suggesting that heat will fully manifest externally. Yet, the patient experiences chills, which contradicts the pulse presentation. Why? This is due to stagnation of Qi and Blood and disharmony of Ying (Nutritive) and Wei (Defensive) Qi. As the classics state, "When Ying Qi does not flow smoothly and reverses into the muscle tissue, abscesses and swellings arise; when Yang Qi is excessive and Ying Qi fails to circulate, abscesses develop." Furthermore, the patient already has a painful area. Since the visible pulse indicates Yang, and the impending pain also belongs to Yang, it is said: "An abscess is likely to develop."

The Master said: Regarding various abscesses and swellings, to determine whether pus has formed, press your hand over the swollen area. If it feels hot, pus is present; if not hot, pus is absent.
[Annotation]
"Various abscesses and swellings" refers to abscesses and swellings of any Yin or Yang nature. Regardless of Yin or Yang classification, to determine the presence of pus in any abscess, one should press the swollen area. Heat indicates that tissue necrosis and pus formation have occurred. Therefore, heat signifies the presence of pus, while lack of heat signifies its absence.
[Collected Notes]
Zhou Yangjun stated: The Master's teaching aims to help practitioners determine if an abscess has matured and is ready to rupture, or if it is immature and requires treatment to promote suppuration and discharge.

Intestinal abscess (Chang Yong, 肠痈) presents with rough, scaly skin (Jiacuo, 甲错), tense abdominal wall, softness upon palpation resembling swelling, but no abdominal masses, no body fever, and a rapid pulse. This indicates pus within the intestines, and Yiyi Fuzi Baijiang San (Coix Seed, Aconite, and Patrinia Powder) is the primary formula.
[Annotation]
When an abscess forms internally, Qi and Blood are consumed by the pathogenic factor and cannot nourish the skin and muscles externally, resulting in dry, rough, scaly skin. The abdominal wall appears tense like swelling, but is soft to the touch. Inquiry reveals no abdominal masses, observation confirms no exterior fever, and pulse diagnosis shows rapidity, indicating no external symptoms. This points to pus accumulation within the intestines. The indicated formula is Yiyi Fuzi Baijiang San, which promotes circulation in the intestines and eliminates abscesses.
