What disease is leg pain when the child is cold and the wind blows?

Hello: Recurrent and incurable leg pain (mostly knee joint) is collectively called old cold leg. The full medical name of old cold leg is "arteriosclerosis obliterans of lower limbs". What does this mean? It is considered that when there are hyperlipidemia and arteriosclerosis plaques in the lower limbs, with the enlargement of plaques, secondary thrombosis occurs, blood vessels narrow, blood flow slows down and blood flow decreases. When the stenosis reaches a certain degree, even the lumen is blocked, and the blood supplied to the lower limbs can not meet the needs, ischemia will occur, which will make the lower limbs feel particularly cold. Although it is explained in this way, is it only the elderly who get this disease clinically? I haven't done any research, but there are many young people, especially lesbians who love cold drinks and patients with indigestion. Generally, the pain will be relieved when it is hot. First of all, in terms of physical fitness, people who love cold drinks or people who don't pay attention to keeping warm due to weather changes, especially some young women, are still fluttering their short skirts in late autumn, which is beautiful but "frozen", resulting in weak body yang, so old cold legs will take the initiative to come to the door. So I want to remind those who have solved hunger. Friends who love beauty and neglect health must keep their mouths shut, and don't let the old cold legs take advantage of it. On the other hand, people with poor digestive ability will lose their ability to convert food into heat. Without heat, they can't resist the cold, and there is no motivation to bring heat to their joints. Can the joint be cold and painless? Secondly, in terms of treatment, since clearing away heat and relieving pain, we should start with improving physical fitness. The body is full of yang, and the cold does not invade. One is to regulate the spleen and stomach, and the other is to tonify kidney and strengthen yang. So, how to regulate the spleen and stomach? Eat less cold drinks and strengthen physical exercise. Huangdi Neijing said: Yang Qi started from four limbs. This means that to replenish Yang Qi, you have to move your limbs. Of course, exercise is the best choice. Who is not hungry after exercise? Who is in poor health after exercise? Can't you see that people walk straight after exercise? Why do you want to tonify kidney and strengthen yang? Traditional Chinese medicine classifies the knee as liver tendon. If the qi and blood of the liver decrease less, the fascia will be malnourished, which is not conducive to exercise. Liver stores blood, kidney stores essence, and essence and blood alternate, so it is also called "homology of liver and kidney". (Note: non-Western liver and kidney mentioned here) Therefore, tonifying kidney and Yang Can recuperate old cold legs. Generally, patients with heart disease, hypertension and diabetes are almost always cold legs, and the yang is too weak, which is not conducive to blood flow. The indigestible food in the stomach is not converted into energy or blood, just like a river without water, which can't be circulated and can't carry heat. Some patients will ask, can there be medicine? In my opinion, as human beings, because of individual surprises, different constitutions and different causes, I hope to understand that there is no ready-made fixed prescription for treatment. It varies from person to person.
