As we all know, the legs and feet, known as the "second heart" of the human body, are closely related to the heart, blood vessels and nerve organs. Some small and inconspicuous changes in the legs may also be early warning signals of some diseases. Only by paying attention to these symptom signals can we better prevent the occurrence of various diseases.
1, cold legs and feet
Some people have cold hands and feet all year round, especially in cold winter, and their legs and feet are even colder. In this case, we should not only consider the physical reasons, but also be alert to the emergence of some diseases.
The most common cause of cold legs and feet is poor blood circulation in lower limbs, such as incomplete vascular valve closure, thrombosis and arteriosclerosis, which will cause blood blockage in legs and feet and insufficient blood supply in legs.
For middle-aged women who often have chills in their legs and feet, accompanied by pallor, eyelid and cheek edema, we should also consider whether it is because of hypothyroidism, which leads to abnormal metabolic function and decreased thermoregulation ability.
For cold legs and feet, suggestions are as follows:
2, numbness in the legs
For numbness in legs and feet, if you just keep a certain posture for a long time, such as sitting, standing or sleeping for a long time, you just need to adjust your posture in time.
However, if numbness of legs and feet often occurs, you should also be careful of numbness caused by cervical spondylosis, lumbar spondylosis and cerebral infarction. Once you have leg numbness and back pain, you should consider whether you have a lumbar disc herniation. At the same time, diabetes can also cause numbness in legs and feet, and early patients often have abnormal feelings such as symmetrical numbness in legs and feet and hot itching.
If there is numbness in the legs and feet, it is recommended that:
3. The color of the legs becomes dark or long spots.
Generally speaking, if the legs are dark or have long spots, there is a great chance of physical problems. For example, when there is a problem in blood circulation, metabolic waste in blood vessels accumulates in the legs, which will lead to the blackening of the legs. Once cancer cells invade, it will lead to a large number of melanocytes proliferation, causing melanoma, and the color of legs will also deepen.
It is recommended for those with black spots or long spots on their legs.
This situation should not be taken lightly. Be sure to go to the hospital in time to check for diabetes and vascular diseases. These changes cannot be ignored.
4, leg itching
The cold and dry weather, especially in winter, is easy to cause dandruff and itching in the legs. For leg skin itching, after eliminating the itching caused by unsanitary hygiene, if it is mild skin itching, first consider whether you have dermatitis. If it is moderate eczema-like itching, we should consider whether it is caused by poor blood circulation. Just like the itching of blood vessels and flesh, you should consider whether you have vasculitis.
However, it should be noted that uremia will lead to the decline of kidney detoxification function, and also lead to the adhesion of metabolites to the skin surface, causing itching. Metabolites produced by cancer cells such as lung cancer and liver cancer can also cause skin itching.
For leg itching, it is recommended that:
5, abnormal swelling and pain in the legs
Pain and swelling in the legs are not uncommon in life. This happens when you knock, touch or walk too much. The swelling and pain in the legs caused by this cause can generally be relieved after rest. However, if there are repeated and frequent abnormal swelling and pain in the legs and feet, it will attract attention.
On the one hand, the leg is abnormally swollen and painful, so be careful of heart disease. The heart connects the important blood vessels and tissues of the whole body, and the thigh has the largest arterial system of the human body. Once suffering from heart disease, it will lead to local vasospasm and even abnormal pain and swelling of the legs.
On the other hand, arteriosclerosis and occlusion of lower limbs can also cause abnormal swelling and pain in the legs. If you have long-term repeated lower limb pain and edema, prominent blood vessels on the skin surface, or even limping, you should be careful. Especially in middle-aged and elderly people, this disease is more frequent, and even causes leg ulcers and necrosis in severe cases. Once there is abnormal swelling and pain in the leg and blood vessels bulge, we should pay attention to it.
For abnormal swelling and pain in the legs, it is suggested that:
These are the common symptoms that lead to leg diseases. As a common leg problem in middle-aged and elderly people, what methods can be improved?
For middle-aged and elderly people, leg maintenance is very important. You can exercise your legs and feet from the following points:
Leg throwing: find a support (such as railing or wall), one leg is fixed and supported, the other leg is lifted and tightened, and the animation circle is thrown into the air. Then change the other leg and do it 5~6 times for each leg. This action can exercise the leg muscles well, promote blood circulation in the leg and balance the body.
Knead the calf: Knead the "Chengshan point" at the calf with both hands, which is the joint of tendons, bones and meat. When you feel uncomfortable with your legs, you can massage here for about 10 minutes each time. Pressing the calf can relieve leg pain and cramps and enhance leg strength.
Tip on tiptoe: This exercise is simple and effective for middle-aged and elderly people. With the help of railings or chairs, hold your chest high and look at your left and right toes at the same time, so that your feet are about 60 degrees off the ground, stand on tiptoe for 5~6 seconds, then lift your forefoot with your feet, and repeat the above actions. Stick to 15 minutes every day, and you can exercise your legs and feet well.
In short, leg health is very important to health, and everyone should exercise leg muscles properly to promote leg health. Once abnormal signals appear, they should be paid attention to and treated in time.
