What causes leg joint pain

We usually hear about rheumatism. One of the symptoms of this disease is that the joints in various parts of the body will be extremely painful and restless. However, rheumatism is extremely difficult to treat and we can only relieve the frequency of the attack and the degree of pain. Leg joint pain may be caused by rheumatism, but it is definitely not just rheumatism that can cause leg joint pain.

Causes of leg joint pain:

1. Cartilage damage is mainly meniscus damage of the knee joint. When the knee joint is slightly bent, 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 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.

2. Injury to the ligaments around the joint: The stability of the knee ligaments is relatively poor when the knee joint is slightly flexed. If it is suddenly subjected to external force and causes 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.

3. Synovitis: When the synovium of the joint is damaged due to trauma or excessive strain, a large amount of fluid will accumulate, which will increase 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 Immune system diseases such as lupus erythematosus and psoriasis can also invade the joints and cause swelling and pain, which requires blood tests to assist in diagnosis.

5. Children's growing pains. This type of patients 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.

6. Traumatic joint pain is caused by some accident or incident that causes trauma (such as soft tissue injury, fracture and dislocation, etc.) to the joints of the shoulder, wrist, knee, ankle, etc. without any serious fractures, resulting in joint pain.

7. Suppurative arthritis has a history of infection in other parts of the body or a history of local trauma. The painful joints may be swollen, and the deep location may not be obvious, but there are symptoms such as increased body temperature, joint pain, inability to move, and increased blood count.
