经云∶诸寒为痛。又云∶痛则为实，内快外痛，为外实内虚，外快内痛，为内实外虚。今痘疮身痛者，是皮
肤浓，肉理密，或为外寒相搏，或热毒内作，或血虚不能荣养，宜审而治之。沧洲翁云∶凡疮发身痛，不
为外寒所折，则肉腠浓密，
宜分而治之。若红点方见，为寒所折，而内体有热，宜木香参苏饮，轻者消毒饮，或葛根升麻加芍药汤。肉腠密者，
宜活血散合匀气散。外寒搏者，必兼有表证，如和解汤、攻毒散去柴胡、前胡，皆可用。若兼发热头痛、恶寒
咳嗽者，参苏饮主之。热毒内作血瘀而痛者，先用活命饮（疮疡），次用消毒救苦汤（痘大法）。血虚而瘀，因作痛者，
四物汤之类。遍身如啮，色黑者，毒瓦斯壅滞而血凝也，乃是危证，若二便秘结、喘急烦躁，用栀子仁汤，或猪尾膏
血调片脑治之。自利不食者，不治。

The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "All pains caused by cold." It also states: "Pain indicates excess. If the exterior feels comfortable while the interior is painful, it is exterior excess and interior deficiency; if the exterior is painful while the interior feels comfortable, it is interior excess and exterior deficiency." In cases of smallpox (Dou Chuang) accompanied by generalized body pain, this occurs because the skin is dense and the muscle texture is tight, or due to conflict with external cold pathogens, or due to internal heat-toxin activation, or due to blood deficiency failing to nourish the body. One must carefully examine the syndrome before treating. Master Cangzhou said: "Whenever sores erupt accompanied by body pain, if not suppressed by external cold, it is due to dense flesh and pores; treatment should be differentiated." If red spots are just appearing, suppressed by cold, yet there is heat in the interior, Muxiang Rensu Yin (Wood-Aromatic Ginseng and Perilla Decoction) is suitable; for mild cases, Xiaodu Yin (Detoxification Decoction), or Gegen Shengma Jia Shaoyao Tang (Kudzu Root and Cimicifuga Decoction with Added Peony) may be used. For those with dense flesh and pores, Huoxue San (Blood-Invigorating Powder) combined with Yunqi San (Qi-Balancing Powder) is appropriate. For those conflicted by external cold, there will inevitably be exterior syndromes; Hejie Tang (Harmonizing Decoction) or Gongdu San (Toxin-Attacking Powder, without Chaihu and Qianhu) can all be used. If accompanied by fever, headache, aversion to cold, and cough, Rensu Yin (Ginseng and Perilla Decoction) is the primary prescription. For pain caused by internal heat-toxin activation and blood stasis, first use Huoming Yin (Life-Saving Decoction, indicated for carbuncles and sores), followed by Xiaodu Jiuku Tang (Detoxification and Suffering-Relief Decoction, a fundamental method for smallpox). For pain due to blood deficiency and stasis, formulas similar to Siwu Tang (Four Substances Decoction) are used. If the whole body feels as if bitten by insects, with black discoloration, this indicates toxic qi stagnation and blood coagulation, which is a critical condition. If accompanied by constipation of both bowels, rapid breathing, and irritability, Zhizi Ren Tang (Gardenia Seed Decoction) or Zhuwei Gao (Pig Tail Paste) mixed with Pian Nao (Borneol) should be used. If spontaneous diarrhea and anorexia occur, it is considered incurable.
