产后全身关节松弛开张，血脉运行散乱，若遇气虚无力推动，则经络、皮肤与肌肉之间血液停滞不散，导致骨节活动不利，筋脉拘挛牵引紧缩，因此出现腰背部僵硬无法转身侧卧，手足不能随意摇动，身体发热并伴有头痛。如果误当作伤寒病来治疗（使用发汗法），会导致汗出过多而筋脉跳动抽搐，手足冰冷，进而引发其他病变。此时应当适宜服用趁痛散。

薛立斋说：产后身体疼痛，如果用手按压后疼痛加剧，这是血滞（瘀血阻滞）的表现，应使用四物汤加炮姜、红花、桃仁、泽兰，以补益兼消散瘀血；如果按压后疼痛稍缓，这是血虚的表现，应使用四物汤加炮姜、白术、人参，以补益兼滋养气血。
有一位产妇，身体疼痛且发热，食欲不振，烦躁不安且失眠，夜间盗汗，服用了解表发散和行血化瘀的药物后，时常出现神志昏沉迷糊的症状，六脉洪大但按之空虚无力（如无）。改用补中益气汤加炮姜、半夏，服用一剂后症状明显减轻，又服两剂后睡眠和饮食恢复正常香甜，但仍有背部僵硬疼痛，随后使用八珍散和大补汤调理而痊愈。
另一位产妇，全身及头颈部疼痛，怕冷且肢体拘急紧张，脉象浮紧，这是风寒侵袭的证候，使用五积散，服用一剂后出汗而痊愈。之后出现倦怠乏力、发热，这是邪气已去但真气虚弱所致，使用八珍汤调补而康复。
After childbirth, the joints and apertures of the body are relaxed and open, and the blood vessels and flow are dispersed. If Qi is weak, blood stagnates and fails to circulate between the meridians, skin, and muscles, leading to stiffness in the bone joints and tension in the sinews and vessels. Consequently, there is an inability to turn or bend the waist and back, immobility of the hands and feet, fever, and headache. If this condition is mistakenly treated as Taiyang Cold Damage (Shanghan) with sweating methods, it will cause excessive sweating, twitching of the sinews and vessels, coldness of the hands and feet, and give rise to other pathological changes. It is appropriate to administer Chentong San (Urgent Pain-Relieving Powder).

Xue Lizhai stated: For postpartum body pain, if pressing with the hand exacerbates the pain, it indicates Blood Stagnation; use Siwu Tang (Four Substances Decoction) combined with Paojiang (Roasted Ginger), Honghua (Carthami Flos), Taoren (Persic Semen), and Zelan (Leonuri Herba) to tonify and dissipate stasis. If pressing slightly relieves the pain, it indicates Blood Deficiency; use Siwu Tang (Four Substances Decoction) combined with Paojiang (Roasted Ginger), Baizhu (Atractylodis Macrocephalae Rhizoma), and Renshen (Ginseng Radix et Rhizoma) to tonify and nourish.
A puerpera presented with body pain, fever, anorexia, irritability, insomnia, and night sweats. After administering dispersing and blood-invigorating herbs, she frequently experienced delirium and confusion. Her six pulses were surging and large yet felt empty upon pressure ("like nothing"). Using Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) plus Paojiang (Roasted Ginger) and Banxia (Pinelliae Rhizoma), her symptoms decreased significantly after one dose. After two more doses, her sleep and appetite improved markedly. However, due to residual stiffness and pain in the back, she was managed with Bazhen San (Eight Treasures Powder) and Dabu Tang (Great Tonifying Decoction) for regulation and recovery.
Another puerpera suffered from generalized pain in the body, head, and neck, aversion to cold, and muscular rigidity, with a floating and tight pulse. This indicated a Wind-Cold pattern. She was treated with Wuji San (Five Accumulations Powder); after one dose, sweating occurred, and she recovered. Subsequently, she experienced fatigue and low-grade fever, indicating that the pathogenic factor had departed but the True Qi was deficient. She was cured using Bazhen Tang (Eight Treasures Decoction) for regulation and tonification.
