游肿之候，青、黄、赤、白，无复定色，游走皮肤之间，肉上微光是也。
日游肿，其候与前游肿相似，但手近之微痛，如复小痒为异。世言犯角日游神之所作。
流肿凡有两候，有热有冷。冷肿者，其痛隐隐然沉深，着臂膊，在背上则肿起，凭
凭然而急痛；若手按及针灸之即肿起是也。热肿者，四肢热如火炙之状，移无常处，或如手
，或如盘，着背腹是；剧则皆热如火，遍身熠熠然，五心烦热，唇口干燥，如注之状。此皆
风邪搏血气所生。以其移无常处，故谓流肿。
疔疮者，风邪毒瓦斯搏于肌肉所生也。凡有十种∶一者，疮头乌而强凹；二者，疮头白而
肿实；三者，疮头如豆 色；四者，疮头似葩红色；五者，疮头内有黑脉；六者，疮
头赤红而浮虚；七者，疮头葩而黄；八者，疮头如金薄；九者，疮头如茱萸；十得，疮头如
石榴子。
亦有初如风轸气，搔破青黄汁出，里有赤黑脉而小肿；亦有全不令人知，忽以衣物触及
摸着则痛，若故取，便不知处；亦有肉突起如鱼眼之状，赤黑惨痛彻骨。久结皆变至粕成疮
，疮下深孔，如大针穿之状。
初作时，突起如丁盖，故谓之疔疮。令人恶寒，四肢强痛，兼忉忉然牵痛，一二日疮便
变焦黑色，肿大光起，根硬强，全不得近，酸痛，皆其候也。在手足、头面、骨节间者
最急，其余处则可也。毒入腹，则烦闷，恍惚不佳，或如醉，患此者，三二日便死。
《养生方》云∶人汗入诸食内，食之作疔疮。
游肿的症状，颜色呈现青、黄、赤、白，没有固定的色泽，在皮肤之间游走，肌肉表面有微光，这就是游肿。
日游肿，其症状与前面的游肿相似，只是手靠近时会有轻微疼痛，或者伴有轻微瘙痒，这是它的不同之处。世人说是触犯了“日游神”角所致。
流肿主要有两种证候，一种是热性，一种是冷性。冷肿，疼痛隐隐然深沉，附着于手臂；如果在背部，则肿胀隆起，凭凭然而剧烈疼痛；如果用手按压或进行针灸刺激就会肿胀起来，这就是冷肿。热肿，四肢发热像火烤一样，移动没有固定位置，有的像手掌大小，有的像盘子大小，出现在背部和腹部；严重时全身都热得像火一样，遍身熠熠发光，五心烦热（手心、脚心及心胸烦热），嘴唇和口腔干燥，像水流注下一样。这些都是风邪与血气搏结所产生的。因为它移动没有固定位置，所以称为流肿。
疔疮，是风邪毒瓦斯搏结于肌肉所生成的。总共有十种：第一种，疮头乌黑且坚硬凹陷；第二种，疮头白色且肿胀坚实；第三种，疮头像豆子的颜色；第四种，疮头像花朵的红色；第五种，疮头内部有黑色的脉络；第六种，疮头赤红而浮虚；第七种，疮头像花朵且黄色；第八种，疮头像金箔；第九种，疮头像茱萸；第十种，疮头像石榴籽。
也有初起时像风疹块的气团，抓破后流出青黄色的汁液，里面有赤黑色的脉络且轻微肿胀；也有完全让人察觉不到的，忽然被衣物触及碰到就感到疼痛，如果故意去取它，就不知道痛处在哪里了；也有肌肉突起像鱼眼形状，赤黑色惨痛彻骨的。久结都会变成腐烂成疮，疮下有深孔，像大针穿过一样的形状。
初发时，突起像丁盖（钉子的盖子），所以称为疔疮。使人恶寒，四肢强直疼痛，兼有忉忉然牵拉痛，一两天后疮便变成焦黑色，肿大光亮隆起，根部硬强，完全不能触碰，酸痛，这些都是它的症状。发生在手足、头面、骨节间的最为急重，其他部位则可以稍缓。如果毒气进入腹部，则会烦闷，神志恍惚不佳，或者像喝醉了一样，患此病的人，两三天内就会死亡。
《养生方》说：人的汗液混入各种食物中，吃了就会生疔疮。
The manifestation of Youzhong (Wandering Swelling) involves colors of green, yellow, red, and white, with no fixed hue, wandering between the skin. The muscles exhibit a slight luster; this is Youzhong.
Youzhouzhong (Day-Wandering Swelling) presents symptoms similar to the aforementioned Youzhong, but differs in that it causes slight pain when the hand approaches or mild itching. It is said in the world that this is caused by offending the "Youzhou Shen" (Day-Wandering Deity).
Liuzhong (Flowing Swelling) generally has two manifestations: one is hot, and the other is cold. In Cold Zhong, the pain is dull and deep-seated, adhering to the arms; if located on the back, swelling rises, accompanied by sudden, severe pain; pressing with the hand or applying acupuncture causes swelling, which characterizes Cold Zhong. In Hot Zhong, the limbs feel hot as if roasted by fire, moving without a fixed location; the swelling may be palm-sized or plate-sized, appearing on the back and abdomen. In severe cases, the whole body feels hot as if on fire, shining brightly, with five-palm heat (heat in the palms, soles, and chest), dry lips and mouth, and a sensation like pouring water. These are all generated by the struggle between Wind Pathogen and Qi and Blood. Because it moves without a fixed place, it is called Liuzhong.
Dingchuang (Carbuncle/Boil resembling a nail head) is generated by Wind Pathogen and toxic vapors struggling in the muscles. There are ten types in total: 1. The sore head is black and hard with a depression; 2. The sore head is white and swollen and solid; 3. The sore head is the color of beans; 4. The sore head resembles the red of flowers; 5. There are black meridians inside the sore head; 6. The sore head is red and floating/vacuous; 7. The sore head is flower-like and yellow; 8. The sore head resembles gold foil; 9. The sore head resembles cornel fruit; 10. The sore head resembles pomegranate seeds.
Some cases initially resemble wind wheals; scratching them breaks the skin, releasing green-yellow fluid, with red-black meridians inside and slight swelling. Some cases are completely imperceptible until suddenly touched by clothing, causing pain; if one tries to locate the source intentionally, the site of pain becomes indistinct. Some present with muscle protrusions resembling fish eyes, with red-black discoloration and bone-penetrating agony. Prolonged stagnation turns into rotting sores, with deep holes beneath the sores, resembling punctures made by large needles.
Initially, they protrude like the cap of a nail (ding), hence the name Dingchuang. They cause aversion to cold, stiffness and pain in the four limbs, along with sharp pulling pains. Within one or two days, the sore turns scorched black, swells, shines, and the root becomes hard and strong, making it untouchable due to soreness and pain; these are its manifestations. Cases occurring on the hands, feet, head, face, and joints are most urgent, while those in other areas are less severe. If the toxin enters the abdomen, it causes restlessness and mental confusion, or a state resembling drunkenness. Patients suffering from this condition may die within two or three days.
The *Yangsheng Fang* states: If human sweat enters various foods, consuming them will cause Dingchuang.
