Coarse joints may be caused by rheumatoid arthritis, gout, osteoarthritis, etc. Different causes are handled differently, but comprehensive treatment using physical therapy, medication, and functional exercises is generally used. Rheumatoid arthritis is the destruction of joint tissues by the immune system, resulting in joints and synovium to produce an inflammatory reaction and cause joint swelling and coarseness. At this time, rest and local braking are required. Anti-rheumatic medication such as methotrexate tablets can also be taken to improve symptoms. After the swelling and pain of the joints are reduced, you can carry out functional exercises for the joints in order to promote local blood circulation and reduce joint enlargement. Inflammatory joint enlargement is caused by high uric acid in the body. If the swelling is in the acute stage, drugs such as colchicine tablets can be taken to improve joint symptoms. If the swelling is in a stable stage, you can take drugs such as febuxostat to improve the symptoms. At the same time, you should try to eat less seafood in your daily life. You can also reduce uric acid in the body and improve joint coarseness through regular physical exercise such as jogging and walking. Degenerative changes in the bones and joints will lead to osteophytes and swelling of the joints, which can be treated by microwave therapy to promote the absorption of local inflammation and reduce swelling and pain. Non-steroidal anti-inflammatory drugs, such as ibuprofen, can also be used to reduce the pain caused by large joints. In addition, under the guidance of a medical professional, you can also perform gradual joint flexion, extension and stretching exercises to improve joint swelling. In conclusion, it is important to visit the hospital in time for proper treatment under the guidance of a doctor when joint enlargement occurs.
