Friends often ask, how do I know if my friend's kidneys are good?
Regardless of whether this friend really exists or not, in fact, to get your answer, you only need to ask him three questions:
1. Ask him if he often has a "toothache"
If a man has a deficiency of kidney yin, and yin deficiency is endogenous, this deficiency will burn the gums, and the person will be prone to swollen and painful gums and chronic toothache. Such people are usually accompanied by dry mouth, night sweats, insomnia, waist and knee soreness and other problems.
2. Ask him if his heel hurts
The kidney meridian starts from our feet, if a man's kidney essence is insufficient, can not nourish the meridians, and the muscles and veins are not nourished, it is easy to have sore and numb legs. Especially in the heels, if you walk a little more, you are prone to soreness and pain, usually accompanied by tinnitus, loose teeth, forgetfulness, and decreased function.
3. Ask him if his back hurts
As soon as many men have back pain, they think they may be tired. But if you have long-term low back pain, especially after interactive combat, the pain will be aggravated, which should be alert to whether it is kidney deficiency. Because the waist is the home of the kidneys, once the kidneys are deficient and the waist is not nourished, there will naturally be pain, soreness, and fatigue. Such people are usually accompanied by weakness in the limbs, numbness, edema, etc.
If one of them has appeared, it is necessary to seek medical attention in time to check it out and prevent it from happening.
