Generally, when performing some heavy physical labor, or some running, brisk walking exercises, and standing for a long time, the knee joint will be painful due to overextension. But with proper rest, this knee pain will soon ease.
Only in daily life, many people enter the winter every time, even if they are in a state of mild labor, the knee joint will have repeated pain, which will seriously affect normal life and health.
So many people want to know, what are the reasons for this phenomenon?
First, stimulated by the cold
Whether it is the elderly or young people, after entering the winter, if the knee joint is repeatedly stimulated by cold, it will cause joint pain.
When the knee joint is repeatedly stimulated by cold, the muscles and ligaments around the joint will spasm abnormally, and the blood circulation around the knee joint will become very slow.
Local painkillers are released in large quantities, resulting in soreness, swelling, and pain in the knee joint. If this factor causes pain in the knee joint, as long as the knee joint is applied warmly, the pain will soon be relieved.
2. High uric acid or gout
After entering the winter, the climate is relatively cold, and many people especially like to eat some foods rich in purines, such as various meats, hot pots and various broths. These foods can provide more heat energy for the human body, and achieve the effect of quickly driving away cold and warming up.
However, if these foods are consumed in large quantities, and when eating these foods, there will be drinking behavior, which will increase the amount of purine substances entering the body. Purines, on the other hand, are metabolized in the human body and produce a large amount of uric acid. The body cannot excrete too much uric acid in time, which will cause hyperuricemia.
If the uric acid value itself is too high, it is very likely to induce the appearance of gout. Then the patient's knee joint is very likely to have repeated pain, swelling, and inflammatory reactions such as skin temperature and fever.
If it is caused by too much uric acid, there may be inflammatory reactions such as redness, swelling, heat and pain in any joint area of the patient. In severe cases, it can even lead to joint deformities and limited mobility.
3. Osteoporosis
Especially for some elderly people, after entering the winter, the climate is relatively cold, the air is very dry, and the elasticity of the human body's bones will become relatively poor. In addition, the time for daily exercise is relatively small, the calcium loss is more, and osteoporosis is prone to occur.
Then, in daily life, patients will repeatedly experience soreness in the knee area or pain in bone joints, and the probability of fractures will increase relatively.
4. Rheumatoid arthritis
Especially in some areas of the north, the climate is very cold in winter, and once the body is not warmed, it will cause the joints to be cold.
The rate of blood circulation becomes very slow, which can lead to edema of the knee synovium and surrounding tissues, which can induce the appearance of rheumatoid arthritis. Then the patient's knee joint will have repeated pain phenomena, as well as local redness and burning sensation.
After entering the winter, if the pain phenomenon occurs repeatedly in the knee joint, it is generally caused by the above four factors. Then, when this happens, it is necessary to quickly go to a regular hospital for a series of examinations and give corresponding treatment according to the cause of the pain.
In addition, we must pay attention to the adjustment of the indoor environment, do not let the indoor temperature be too low, and do not let the indoor moisture be too much. When going out, do a good job of keeping your body warm.
If you are attacked by cold air, you should quickly apply heat to the knee joint, which can effectively avoid the phenomenon of knee joint pain.
