《黄帝内经·灵枢·寿夭刚柔》
卫有病则痛无定处，也不定时，胸腹会感到满闷或者窜动作响，这是风寒侵袭于肠胃所致。
卫之生病也，气痛时来时去，怫忾贲响，风寒客于肠胃之中。
If the Wei is diseased, then the pain has no fixed place and time of occurrence, as well as a feeling of fullness or rumbling in the chest and abdomen, which is the result of the invasion of external cold into the stomach and intestines.
