What should I do if the weather turns cold and my knee hurts?

It mainly happens to young people. This is because a large number of young people wear less clothes (or beggars' clothes with holes in their knees), which makes joints with low muscle and fat content lack protection. When the weather gets cold or the temperature drops suddenly, local blood vessels and muscles contract, resulting in temporary ischemic injury of muscles and soft tissues at joints, thus causing pain.

Relief mode: moderately strengthen exercise and get some relief after adapting to the surrounding environment.

Second, osteoarthritis.

The main symptoms are pain, soreness and discomfort, which mostly occur after activities (when going upstairs and downstairs) and can be relieved after rest. With the progress of the disease, it is difficult to walk and squat gradually, and I can't stand steadily at first in the morning until I stand for a while. It mainly occurs after the age of 40 and has little to do with environmental changes.

There is no specificity in laboratory examination, and the typical X-ray manifestations are subchondral sclerosis, cystic degeneration, osteophyte formation at the joint edge and narrowing of joint space.

Third, rheumatism.

Rheumatism is a recurrent systemic connective tissue inflammation caused by B hemolytic streptococcus infection, which mainly involves joints, heart, skin and subcutaneous tissue. Today, we mainly introduce the forms of participation. Rheumatoid arthritis mainly involves knee, ankle, shoulder, elbow, wrist and other major joints, showing wandering and multiple manifestations, with local swelling and heat pain. With the cold weather and rain, the pain will recur and get worse.

Fourth, rheumatoid arthritis.

The onset age of 80% patients is 35-50 years old, which is mainly manifested as morning stiffness (stiffness around joints after morning stiffness, lasting more than 1 hour). The joint pain is symmetrical and wandering, which first occurs in wrist joints, finger joints, metacarpophalangeal joints and proximal interphalangeal joints, and gradually develops to toes, knees, ankles, shoulders and elbows. Joint deformity can occur in the late stage.

Treatment: Rest and joint immobilization should be strengthened in acute stage. Chronic phase can strengthen joint exercise. Drugs: Non-steroidal anti-inflammatory drugs can relieve fever and pain, anti-rheumatic drugs (methotrexate is the first choice) can improve the condition, in addition to glucocorticoid, biological targeted therapy, and artificial joint replacement.

Verb (abbreviation of verb) abstract

1. If there are no other problems, leg pain caused by cooling or weather changes in young people is generally temporary ischemic pain caused by vasoconstriction, so it is good to strengthen exercise.

Middle-aged or elderly people should be alert to frequent leg pain. With the increase of age, osteoporosis and degenerative changes of joints are prone to occur. Specifically, it is necessary to seek medical treatment as soon as possible and treat it in time.
