Difference between Jie Xiong and Pi Zheng

Line 131 tells us that both are caused by 误下. However, whether the body is yin or yang when the precipitation happens will decide on what happens.

“病发于阳，而反下之，热入因[而]作结胸；”

“病发于阴，而反下之，因[而]作痞也。”

There are several explanations for what yin  and yang mean here. But a commonly accepted explanation is that yang refers to a pathogen that has form – 痰水 – which is sort of pulled into the chest area due to the precipitation; while yin refers to a pathogen that is without form – 气 – which is similarly pulled into the chest area by the act of precipitation.

Which then make sense if we accept the common definition that a 痞 is soft and not painful when pressed, while a 结胸 is hard and painful when pressed.
