Treatment of swollen joints needs to be based on the specific cause of the swelling, which can be divided into two main categories: 1. Injury to the joint. If the joint injury is relatively mild, such as strain of muscles, tendons, ligaments, etc., proper rest should be given and continued activity should be avoided. The general application of anti-inflammatory and pain relief, blood circulation and muscle relaxants, after 3-5 days, the symptoms can be significantly reduced after the edema period is over. If there is a significant major injury, such as fracture, dislocation, meniscus or cruciate ligament damage, conservative and surgical treatment is required depending on the extent of the injury. If there is a significant displacement of the fracture, a significant tear of the meniscus, or a significant strain of the cruciate ligament, surgical treatment is generally indicated. In addition, you can carry out external fixation of plaster and brace for conservative treatment.2. Bone diseases, such as osteoarthritis, rheumatoid arthritis, rheumatoid arthritis, gouty arthritis, tuberculous arthritis, which can cause enlargement of the joint. Therefore, treatment should be tailored to the specific disease. In the case of osteoarthritis, rest, avoiding activities and swimming, and intra-articular injections of hormones and sodium vitreous lubricant are usually required to reduce symptoms. In the case of gouty arthritis, it is important to reduce the consumption of purine foods, such as animal offal, spinach, soy products, and beer, which can cause an increase in uric acid, which can lead to gouty arthritis. In case of rheumatic or rheumatoid arthritis, immunosuppressants should be applied to control the immune response on top of anti-inflammatory and analgesic drugs. In the case of tuberculous arthritis, anti-tuberculosis treatment is required. Therefore, swollen joints need to be treated according to the specific situation.
