The point St 36 may be saving you from going to the emergency room when you have colic from kidney stones. Normally a needle is used, but you may try with a strong massage or even cooling the spot with ice cubes.
There are some other points, but these are a bit more difficult to explain. The lady is explaining really well, but she mentions the point for other indications which are all right. I am sending you this for emergency treatment…kidney colics.
