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。
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.
