Why does it always hurt your knees in rainy days?

Sichuan Modern Hospital reminds you that this is probably due to knee arthritis. In rainy weather, the temperature will decrease, at this time, the air pressure will increase, and the cell fluid will be stored in the interstitial space. This regulation is the normal function of the organization. In patients with knee arthritis, due to the pathological changes of joint tissue, this regulation function is abnormal, which makes the pathological tissue unable to excrete intracellular fluid with the change of external temperature, resulting in the pressure in local cells higher than that in surrounding normal tissues, thus causing pain and swelling. Therefore, when the weather changes, it becomes cold and rainy, and patients often feel unwell all over, and knee pain or pain intensifies. So, what about knee pain? First of all, pay attention to keep warm, close doors and windows, and reduce the entry of wind, cold and moisture. Wear more pants in cold weather, and don't wash your feet or take a cold bath in hot weather. Wear pants when you turn on the air conditioner. Secondly, pay attention to strengthening leg exercise to enhance the strength of surrounding muscles, promote local blood circulation and increase the stability of knee joint; The most important thing is to receive active treatment. Thirdly, patients with knee arthritis should avoid overwork or knee joint overload, and try to go up and down stairs, climb mountains, stand for a long time and lift heavy objects as little as possible; Try to avoid obesity and prevent the burden on the knee joint from increasing. For overweight people, we should actively lose weight and control weight. Finally, avoid sitting and standing for a long time, often change posture, and prevent the knee from fixing a posture with too much force. People with swollen joints and severe pain should rest. Avoid squatting, carrying loads, going up and down stairs and other activities. If it is still not relieved, it is recommended to go to a professional orthopedic hospital for examination to avoid the deterioration of the condition.
