背部属阳，腹部属阴，五脏的背俞穴（脏腑之气输注于背腰部的穴位）都位于背部。如果乳母不善于照顾婴儿，让婴儿在风中脱衣受凉，背部就会受到外来风邪的侵袭，若未能及时发散解表，寒气就会侵入骨骼的俞穴，导致背部高高隆起，形状像乌龟一样，因此称为“龟背”。或者因为婴儿骨骼稚嫩，过早让其坐立，也会导致脊柱弯曲驼背。必须尽早治疗，以免形成难以治愈的陈旧性疾病。
疏风饮

足部和膝盖是三阴经络脉运行汇聚的地方，这里多气少血，容易受到寒邪侵袭，导致气血凝结而不散。病症起初表现为寒热交替，若失于发散，寒气客居于膝骨之中，会导致日夜疼痛，早晨轻晚上重，大腿和小腿肌肉消瘦萎缩，膝盖粗大浮肿，几乎像鹤的膝盖一样，因此得名。这也被称为“鹤膝风”，又名“鼓槌风”，病证相同但名称不同。切不可以使用寒凉性质的外敷药物，也不宜擅自使用刀针穿刺，一旦误用这些方法，大多会导致病情恶化无法挽救，实在令人怜悯。听说即使有治愈者，也会终身残疾。外敷药物宜用温热性质，内服药物也宜用温性，待寒气消散，肿胀自然消除。

The back belongs to Yang, and the abdomen belongs to Yin. The Shu points (Acupoints where the Qi of the Zang organs is transported) of the five Zang organs are all located on the back. If the wet nurse fails to care for the infant properly, exposing the child's bare back to the wind, the back will be struck by exogenous Wind pathogens (Ke Feng). If this pathogenic factor is not resolved and dispersed in time, Cold Qi will enter the bone Shu, causing the back to protrude high like a turtle shell; hence it is called "Turtle Back" (Gui Bei). Alternatively, if the infant's bones are tender and soft, sitting them up too early can also cause kyphosis (stooping). Early treatment is necessary to prevent the formation of chronic, incurable diseases.

The feet and knees are the sites where the meridians of the Three Yin channels run and converge. This area has abundant Qi but scarce Blood. When invaded by Cold Qi, the Qi and Blood knot and fail to disperse. The condition initially presents with alternating chills and fever. Due to failure to disperse the pathogen, Cold Qi lodges within the knee bones, causing pain day and night, which is lighter in the morning and heavier at night. The muscles of the upper and lower legs waste away, while the knees become coarse and swollen, resembling the knee of a crane; thus it is named accordingly. It is also called "Crane Knee Wind" (He Xi Feng) or "Drumstick Wind" (Gu Chui Feng); the pathology is the same, but the names differ. One must absolutely avoid using cold-natured topical applications, nor should one arbitrarily use knives or needles. Misuse of these methods often leads to untreatable conditions, which is truly pitiable. Those who survive may suffer lifelong disability. Topical applications should be warm in nature, and internal medications should also be warming. Once the Cold Qi dissipates, the swelling will subside naturally.
