胁痛因瘀血阻滞侵犯肝经，左侧多属血分病变，右侧多属气分病变，需仔细分辨。血分瘀滞可用延胡散治疗，气分郁滞适宜用四君子汤加柴胡、青皮。若因产后失血过多导致的虚性疼痛，宜用八珍汤加肉桂以补益营血。
腰痛向下放射至大腿疼痛，多因风冷之邪停留，导致瘀血阻滞于经脉。可用佛手散加独活、肉桂，或选用续断、牛膝、桑寄生。若因产时失血过多损伤三阴经气血，宜用地黄丸（此处指六味地黄汤类方）加肉桂、附子、续断、杜仲进行温补。
趁痛散适用于产后身体疼痛，若因营血不足所致；若因外感客邪引起，则表证先现。趁痛散由当归、黄芪、白术、牛膝、甘草、独活、薤白、桂心组成。若见面部嘴唇紫胀、身体疼痛，必是瘀血停滞所致，宜用四物汤加秦艽、桃仁、没药、红花以活血化瘀。
Hypochondriac pain caused by blood stasis invading the Liver meridian: lesions on the left are predominantly of Blood, while those on the right are predominantly of Qi; these must be clearly distinguished. For Blood stasis, Yanhu San (Corydalis Rhizome Powder) is indicated; for Qi stagnation, Sijunzi Tang (Four Gentlemen Decoction) added with Chai Hu (Bupleuri Radix) and Qing Pi (Aurantii Fructus Pericarpium) is suitable. If the pain is due to deficiency from excessive blood loss, Bazhen Tang (Eight Treasure Decoction) added with Rou Gui (Cinnamomi Cortex) should be used to tonify Ying Blood.
Lower back pain radiating to both thighs is caused by wind-cold retention and blood stasis obstructing the meridians. Foshou San (Hand-holding Powder) added with Du Huo (Angelicae Pubescentis Radix) and Rou Gui (Cinnamomi Cortex), or Xuduan (Dipsaci Radix), Niu Xi (Achyranthis Bidentatae Radix), and Sang Jisheng (Taxilli Herba) may be used. If excessive blood loss during childbirth injures the Qi and Blood of the Three Yin meridians, Liuwei Dihuang Tang (Six-Ingredient Rehmannia Decoction) added with Rou Gui (Cinnamomi Cortex), Fu Zi (Aconiti Lateralis Radix Preparata), Xuduan (Dipsaci Radix), and Duzhong (Eucommiae Cortex) should be employed for warming and tonification.
Chentong San (Pain-Relieving Powder) is indicated for postpartum body pain due to deficiency of Ying Blood; if caused by external pathogenic invasion, exterior symptoms appear first. Chentong San consists of Dang Gui (Angelicae Sinensis Radix), Huang Qi (Astragali Radix), Bai Zhu (Atractylodis Macrocephalae Rhizoma), Niu Xi (Achyranthis Bidentatae Radix), Gan Cao (Glycyrrhizae Radix et Rhizoma), Du Huo (Angelicae Pubescentis Radix), Xie Bai (Allii Macrostemonis Bulbus), and Gui Xin (Cinnamomi Ramulus). If the face and lips are purple and swollen with body pain, it is necessarily due to retained stasis; Siwu Tang (Four Substances Decoction) added with Qin Jiao (Gentianae Macrophyllae Radix), Tao Ren (Persicae Semen), Moyao (Myrrha), and Hong Hua (Carthami Flos) should be used to promote circulation and resolve stasis.
