A man in his 40s came to the clinic. The reason for his registration was “prominent green tendons” on the back of his hand. Someone told him that it was blood stasis caused by phlegm dampness and heat toxin. He was advised to take medicine to recuperate.
because the medicine prescribed for him required thousands of yuan, he hesitated. After listening to a friend’s introduction, he found me. I said that first of all, I was a cardiologist. This was definitely not a heart disease. Even if he wanted to see it, he would go to another department. Know what you know, you can’t fool around. However, there is no need to see the so-called green tendon on the back of the hand. After all, you can return the number when I finish talking about it. After all, it’s very tiring to move things every day. Maybe you have to move a lot of things for more than ten yuan.
the so-called green muscle is not green muscle, but blood vessel, which is our vein blood vessel. Each of us will have such “green muscle”, but some people can see it, it is very obvious, while others are not.
when we go to the hospital, nurses prefer the relatively obvious “green tendons”, that is, venous blood vessels, because we have to draw blood and infusion through the veins on the back of the hand. Only when you can see it clearly, you can get it right.
the blood vessels in our body are divided into arterial blood and venous blood vessels. The blood in the arterial blood vessels is arterial blood, which is rich in oxygen and appears red; while the venous blood is venous blood, the oxygen content of venous blood is relatively low, and it is dark red when blood is drawn out. Sometimes encounter anoxia patient, the blood that draws out even blackens, this is because anoxia.
one of the main reasons why these veins look cyan is that the skin absorbs and reflects light. The skin near the vein reflects less red light, blue light is more difficult to penetrate the skin, most of it will be reflected back, which is why the veins we see appear blue.
the main reason is that thin people and white skin have relatively good light transmission, so you can see clearly. Fat people, subcutaneous fat is thicker, or the skin is darker, it is not easy to see.
another main reason is that manual workers, most farmers or workers who exert too much forearm strength, and even some sports enthusiasts or athletes, will have “obvious green tendons”. Long term forearm exertion, labor or exercise need more blood supply, long-term blood flow speed is fast, large flow, over time, will lead to thicker blood vessels. So the muscles and blood vessels of these people are more obvious, and they look like green tendons.
it is mainly the venous blood reflux. With the blood stasis in the vein and the increase of the venous pressure, over time, it can lead to the expansion, expansion and tortuousness of the involved vein wall. The tortuousness is often in the form of cords and lumps, which leads to the “blue muscle bulge” of the leg.
most patients have no obvious symptoms of discomfort. If varicose veins continue to worsen, complications, such as ulcer, bleeding, superficial phlebitis, etc., will occur.
some patients may have heavy fatigue and mild edema of lower limbs; symptoms of standing for a long time and feeling in the afternoon are aggravated; symptoms are obviously relieved when lying flat or raising lower limbs; sometimes leg muscle spasm occurs. Sometimes it can be complicated with thrombophlebitis and acute lymphangitis.
in a word, the “green muscle” on the back of the hand is actually a normal vein. Because everyone’s skin, fat and thin, the nature of previous labor, upper limb strength, normal activities or sports and so on, some people have “obvious blue veins”, while others “have no blue veins”.
this kind of green muscle is not blood stasis caused by phlegm dampness and heat toxin, it is not a vascular disease, it is not a varicose vein, it is not a thrombus, it is not a sign of disease.
