There is an acupoint at the arterial pulse at the top of armpit, which is called "extreme spring". Chinese medicine believes that acupuncture or massage at Jiquan point can prevent and treat heart disease, scapulohumeral periarthritis and mastopathy.
In daily life, we can prevent the above diseases by tapping (or tapping with empty fists) or kneading. By tapping the armpit, it can also promote the detoxification of the body's liver and gallbladder. It is convenient to do it after waking up every morning or before going to bed at night. Every time you pat your armpit, it's a multiple of 9. I suggest you pat it at least 36 times, first left and then right.
Some people will have a relatively large lump when touching the armpit, indicating that the blockage of meridians is more serious. It needs to be patted or kneaded for a long time, so that the meridians on the armpit are gradually dredged and the lump gradually recedes.
It is normal for some people to feel more pain and have a red or purple rash when they start beating their armpits. If you feel unbearable pain, you can pat it first and gradually exert yourself according to your tolerance.
Physical conditioning needs to be gradual, and it takes a certain amount of time and process. Blocked meridians need a little dredging, and persistence is very important.
