What is "old cold leg"
Knee osteoarthritis, commonly known as old cold legs, is a common disease that plagues many elderly people, mainly manifested as joint swelling and pain. Its pain is aggravated during exercise and can be relieved after rest. This disease tends to get worse in cold seasons and rainy days. At the initial stage, it is often manifested as knee joint discomfort, and pain and swelling gradually appear, and even the activity is unfavorable and the joint is deformed. The attack time gradually evolved from once a year to discomfort in winter or cold every year.
The knee joint consists of three bones. Under normal circumstances, there is a transparent elastic structure on the surface of articular bone, which is called cartilage. Cartilage is like a shock-absorbing spring of a car. Joints will deform when moving, increasing the contact area between two bones, thus reducing the wear between joints. With the increase of age, articular cartilage will gradually age, not only become thin and brittle, but also break or even fall off in a large area due to trauma. If cartilage wears away, it becomes a "raw mill" between bones during activity. This hard wear of joints will lead to aseptic inflammation, pain, redness, joint stiffness and other symptoms, and induce knee osteoarthritis.
According to the severity of the disease, "old cold legs" are divided into mild, moderate and severe:
Old cold legs are mainly manifested as articular cartilage degeneration and secondary bone hyperplasia around joints, which are more common in middle-aged and elderly people, especially women. When people reach a certain age, all organs of the human body will degenerate, and articular cartilage is no exception. Articular cartilage will become thinner, softer, lose elasticity, and even break, and the bones under the cartilage and its surroundings will proliferate to form osteophytes. In fact, in layman's terms, the joints have been used for many years, and they are old, worn and worn out, just like the tires of cars. After a certain number of years of use, problems will occur. Pain is the most prominent manifestation of old cold legs, and joint pain is characterized by aggravation after exercise and alleviation after rest. Joint pain is paroxysmal at first, and cold and mild trauma can induce or aggravate the pain. Some people only commit it once in a year or two at first. With the progress of the disease, the attacks become more and more frequent, and finally they turn into discomfort such as knee pain and "cool breeze" every winter.
How to relieve discomfort symptoms
1, pay attention to keep warm, and be sure to add clothes when the temperature drops suddenly, especially to protect the knee joints of lower limbs. Keeping warm is a simple and effective means of prevention and treatment, and it is the focus of prevention and treatment of old cold legs. Many ladies who love beauty are still wearing thin stockings at this time. Personally, I think it is not desirable. Everyone loves beauty, but don't sacrifice health.
2. Keep the room warm and dry, and avoid living in wetlands.
3. Non-load aerobic exercise is recommended. Pay attention to the quadriceps exercise.
How can we avoid old cold legs?
After all, cold legs are normal degeneration of knee joint, but everyone has different degrees of degeneration. In order to prevent the knee joint from degenerating so quickly, we suggest controlling the weight, avoiding too frequent mountain climbing, stairs climbing, repeated squats and other sports methods, and it is not recommended to wear high heels often.
It is worth mentioning here that old cold legs are no longer the "privilege" of the elderly. At present, many young girls have symptoms similar to old cold legs at a young age. Knee discomfort occurs on cloudy days or when the temperature drops. The reason is actually caused by "stockings". Although cold is not the direct cause of osteoarthritis, many girls love beauty in winter. In order not to look bloated, the combination of "boots+stockings+miniskirts" is very common. This dress is really beautiful, but it's also freezing. As the largest and most complicated joint in human body, the knee joint has less fat around it. In winter, girls wear too little, their knees are excessively cold, local blood vessels are excessively contracted, joint fluid secretion is reduced, and joints are more vulnerable to indirect injuries. So this kind of people will have symptoms similar to old cold legs very early, so we call for keeping warm in winter and dressing up on this basis.
