What is the reason for joint pain

If you always feel soreness in your bones and joints, don't stand or walk for a long time. You can rest in bed more often. Don't do any physical labor in normal times. These will make your symptoms gradually become more serious. If it doesn't get better after resting in bed for a period of time, you can only go for some examinations to avoid ligament injury.

1. Ligament injury

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

It is mainly a meniscus injury of the knee joint. When the knee joint is slightly flexed, if the knee is suddenly excessively internally rotated or externally extended, 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. Synovitis

When the synovial membrane of the joint is damaged due to trauma or excessive strain, a large amount of fluid will accumulate, increasing the pressure within the joint, leading to joint pain, swelling, tenderness, and frictional 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 and psoriasis can also affect the joints and cause swelling and pain.

5. Growing pains in children

This type of patients are mainly children in the growing 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.

6. Traumatic joint pain

Due to some kind of accident or incident, the joints of the shoulder, wrist, knee, ankle, etc. may suffer trauma (such as soft tissue injury, fracture and dislocation, etc.) without any serious fracture, causing joint pain.

7. Septic arthritis

There is 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.

8. Osteoarthritis

The onset of osteoarthritis is mostly after the age of 40. Joint pain is worse in the morning and gets better during the day and night. Bone hyperplasia and bone spurs in the joints rub against surrounding tissues, causing joint pain.
