Is the old cold leg really frozen?
And how to prevent it?
The fawn will come with you to find out!
"Old cold legs" is actually knee osteoarthritis, which is a common chronic joint disease and is not caused by rheumatism. Clinically, it is mostly caused by osteoarthritis of the knee.
Old cold legs" performance:
Intermittent dull pain in the knee, and when I sleep at night, I feel that "the knee joint is uncomfortable".
There is a friction sound when the knee joint is moving, and some people suddenly feel that the knee joint is "locked" after sitting for a long time, and the knee joint pain is unbearable when going up and down the stairs.
Persistent knee pain or nighttime pain, or even deformation of the knee.
Many older people are susceptible to knee osteoarthritis. As we age, the body's ability to absorb nutrients continues to decline, resulting in degeneration and fibrosis of the knee joints, and the bones and joints become stiff and lose flexibility.
In addition, nutrient deficiency will cause insufficient secretion of synovial fluid in the joint, resulting in a decrease in the water content in the cartilage, a lack of elasticity of the joint tissue, and a serious decrease in the ability to protect against external dangers. At this time, in order to ensure the bearing capacity of the joints, the human body will undergo bone hyperplasia, which will lead to osteoarthritis of the knee joint.
Endocrine disorders are one of the important factors causing knee osteoarthritis, because endocrine disorders can cause intestinal dysfunction, hinder the body's effective absorption of nutrients, and lead to an increase in knee bone and joint fragility. In daily life, obese people and postmenopausal women are more likely to suffer from the disease.
In many families, parents have osteoarthritis of the knee and pass it on to their children. When children are young, they are energetic and absorb nutrients well, so the disease is not easy to detect, but as they age, the symptoms may gradually become exposed.
Knee osteoarthritis can be triggered by intra-articular fractures, dislocations, and meniscus or ligament injuries. Athletes and fitness people are prone to trauma to bones and joints due to various external factors during exercise, burying hidden dangers.
People who need to sit upright for a long time in daily work or study do not get the proper exercise of their bones and joints, resulting in degeneration, and they are also the people with a high incidence of knee osteoarthritis.
The cold itself does not cause articular cartilage lesions, so there is no direct causal relationship between cold and old cold legs. However, the decrease in temperature will cause a series of changes such as vasoconstriction, poor blood circulation, irritation of the synovium of the joints, muscle tension, and joint stiffness, which will aggravate the symptoms of the knee. In this sense, there is also a certain correlation between cold and old cold legs.
If the cold has caused discomfort in the knee joints, or if the legs feel cold for a long time, autumn pants should be worn
Keeping warm is a simple and effective means of prevention and prevention, and it is the focus of the prevention and treatment of "old cold legs". When the temperature drops suddenly, be sure to add clothing, especially to protect the knee joints of the lower limbs.
Keep the room warm and dry, and the bedding should not be too damp.
Do some non-weight-bearing aerobic exercise, such as swimming.
For friends who do not have the conditions, you can do quadriceps muscle exercises, and the specific methods are shown in the figure below.
It can be symptomatic oral administration of some anti-inflammatory and analgesic drugs, external use of some plasters or ointments are OK, and then combined with drugs to nurture cartilage.
If you often feel joint pain, especially if the symptoms worsen when the weather changes, it is recommended to consult a doctor or medical professional for diagnosis and**.
Exercise is an effective way to prevent knee osteoarthritis, but exercise must follow the principle of moderation, whether it is time or intensity, and do not exceed the range that the individual can bear.
Warm up well before exercising. Pay attention to avoid mechanical damage to the joints, and avoid emergency stops and sharp turns.
In daily life, it is best not to let the joints stay in one position for a long time, and long-term stilted legs and sitting for a long time may cause damage to the joints.
When the knee joint needs to be flexed and extended to bear weights, such as going up and down stairs or squatting, the knee joint buckle will cause additional pressure and wear and tear on the articular cartilage. By flexing and extending with the right way of force, reducing the buckle and reducing the forward thrust of the knee, you can reduce the wear and tear of the joints.
Excess weight causes a large load on the knee joint and aggravates joint wear and tear.
