As the seasons change and the temperature drops, joint pain starts to affect people, causing inconvenience to their lives and work. Why does colder weather cause arthritis pain to flare up? The reason is that the cold (especially the constant cold and the huge temperature contrast) can cause muscle and blood vessel contraction, which can lead to joint pain. This is why there is a significant increase in joint pain during the transitional fall and winter seasons when the weather elements change dramatically. There are numerous causes of joint pain. In addition to osteoarthritis, which is most commonly caused by degeneration, it may also be associated with some other diseases of the body, such as rheumatic and rheumatoid arthritis, and joint pain can also be caused by tumors, tuberculosis, certain blood diseases and acute infectious diseases. Therefore, once there is unexplained joint pain, you should not be paralyzed and should go to the hospital for examination and treatment in time to avoid unexpected damage. How to deal with joint pain in daily life? First of all, you should pay attention to the warmth of the affected joints, such as hot water bags for warm compresses. Secondly, the activities of the joints should be reduced during the acute pain period, such as reducing walking, running, climbing and hiking, so that the joints can get sufficient rest to facilitate the repair of the joints. Third, you can take some non-steroidal anti-inflammatory and analgesic drugs for a short time or use anti-inflammatory and pain-relieving creams locally to relieve the symptoms. Fourth, if the above methods still do not work, you must go to the hospital in time to receive systematic treatment. Osteoarthritis is a common chronic disease, whose early symptoms are mainly localized swelling and pain in the joints; in the late stage, it causes joint deformity. In the early stages, the pain is often not serious, and the affected joints are often only sore or mildly painful, with symptoms worsening after weather changes or exertion and decreasing after rest. With the development of the disease, swelling of the joint occurs; in the late stage, due to the protective spasm of the muscles around the joint and the destruction of the joint structure, it can lead to partial or total loss of joint function, morning stiffness, inflexibility, and the formation of bone spurs and other symptoms. Prevention of osteoarthritis is important to slow down the further development of the disease. From a young age, it is important to pay more attention to joint health care, maintain a normal weight, avoid obesity, prevent overexertion, avoid putting joints under long-term stress, and change bad habits such as excessive alcohol consumption to reduce the risk of osteoarthritis. A comprehensive approach to diet and exercise not only reduces the chance of developing degenerative arthritis, but also delays the degeneration of the joints. Appropriate exercise is particularly important to control the progression of the disease. You can choose mild exercises with low impact, such as walking, playing tai chi, moving the waist and hip or limbs in situ, etc. Depending on your condition, activities that cannot be done at once can be completed in stages. If the conditions are limited (such as not being able to go outdoors) or overweight patients, they can also move their joints indoors by changing positions, stretching their waists and sides, lifting their legs and hands, etc., so as to relieve the stiffness of limbs and joints. At the same time, exercise should be gradual, choose some recreational activities, and the exercise can be diversified, as long as the whole body and limbs can “move” is good.
