《黄帝内经·素问·标本病传论》
脾病则先身体沉重疼痛，一日后病邪传入于胃，发生腹胀；再过二日病邪传于肾，发生小腹、腰椎疼痛，小腿发酸；再过三日病邪入膀胱，发生背脊筋骨疼痛，小便不通；再过十日不愈，就要死亡；冬天死于亥时，夏天死于黄昏。
脾病身痛体重，一日而胀，二日少腹腰脊痛、胫酸，三日背𦛗筋痛，小便闭。十日不已，死，冬人定，夏晏食。
The initial onset of spleen disease is a heavy, sore body; after a day, the pathogenic factor will spread to the stomach, causing bloating; if it is not cured after two more days, the pathogenic factor will spread to the kidneys, causing pain in the lower abdomen and lower back, as well as leg cramps; if it is not cured after three more days, the pathogenic factor will spread to the bladder, causing pain in the glutes, spine and bones, and urination issues; if it is not cured after ten more days, death will occur; in the winter, death will occur in the early hours of the morning, and in the summer, death will occur at dusk.
