What causes migratory pain in large joints?

In daily life, many people are often troubled by arthritis. There are many reasons for arthritis and joint pain. Local strain due to age, soft tissue injury, synovitis and other diseases are all important causes of bone problems. After the onset of the disease, you should seek medical attention in time, receive symptomatic treatment, and choose appropriate methods to relieve the symptoms according to the condition.

1. Injury of periarticular ligaments: The stability of the knee ligaments is relatively poor when the knee joint is slightly flexed. If it is suddenly subjected to external force causing eversion or inversion at this time, it may cause injury to the medial or lateral collateral ligament. The patient will have a clear history of trauma, knee pain, swelling, bruising, and limited motion.

2. Cartilage damage is mainly meniscus damage in the knee joint. When the knee joint is slightly flexed, if the knee is suddenly excessively internally rotated or externally extended (for example, when playing football, bending the calf, turning around and kicking the ball), it may cause a meniscus tear. Meniscus injury will cause an obvious tearing feeling in the knee, followed by joint pain, limited movement, limping when walking, and popping when the joint moves.

3. When the synovium of the joint is damaged by trauma or excessive strain, a large amount of fluid will accumulate, increasing the pressure inside the joint, leading to joint pain, swelling, tenderness, and friction and astringent sounds. For example, when the knee joint is actively and extremely extended, especially when the knee extension exercise is performed with a certain resistance, the pain below the patella will be aggravated. The pain is also significantly aggravated during extreme passive flexion.

4. Autoimmune system diseases Autoimmune system diseases such as lupus erythematosus and psoriasis can also affect the joints and cause swelling and pain, which require blood tests to assist in diagnosis.

5. Patients with growing pains in children are mainly children in the growth period, and boys are more common. The pain is commonly found in the knee joint, hip joint, etc. This situation is a normal physiological phenomenon that occurs during children's growth and development. Because the bones of children in the growth stage grow relatively quickly, the growth and development of the periosteum and local muscles are not coordinated, which causes discomfort and joint pain. It is also believed that the pain is caused by a low-grade infection.
