The palm belongs to Laogong point, on the pericardium meridian of Jueyin; The arch of the foot is Yongquan point, which is located on Shaoyin Kidney Meridian. The main function of pericardium meridian is to replace the heart, that is to say, if there is something wrong with the heart, the pericardium meridian will certainly react.
In the basic theory of traditional Chinese medicine, the heart belongs to "fire" and the fire is in the world; Kidney belongs to "water", which is lower. Only when fire and water intersect can we achieve such an effect: water will not always flow downwards; Fire doesn't always go up-fire and water can spread all over the body and achieve a healthy balance. It is conceivable that if fire and water are in opposite positions, or do not meet, then a certain part of the body will be short of water/fire; In fact, any part of a healthy human body is balanced by five elements, otherwise it is morbid.
Of course, your condition should be only mild "heart and kidney failure", but it will definitely get worse when you get older, causing other health problems.
In fact, the human body has a "master valve" to adjust smoothly: in Chinese medicine, where is the center of the human body? This is the position-manhole! The up-and-down communication within the human body depends on him: people who look at faces can judge whether a person's natural life span is high or low just by looking at people. The flatter the acupoints on a person, the more serious the disharmony between heart and kidney-you can verify it according to this: of course, you need to observe it carefully.
In short, rubbing your own acupoints often has various benefits for you. -If you don't want to take medicine, there's no need to get rid of that discomfort quickly.
