There are many causes of synovial membrane hyperplasia, including long-term overuse, external irritation or exposure to cold. Treatment includes physical therapy, medication and surgery, etc. The specific treatment plan depends on the severity of the disease. 1. Physical therapy: Synovial hyperplasia may cause aseptic inflammation, which may lead to localized pain and limitation of activities. Physical therapy and medication can be given locally to alleviate the pain and improve the limitation of activities. 2. Medication: If the pain is severe after synovial hyperplasia, non-steroidal drugs such as diclofenac sodium can be taken orally to eliminate the local inflammation and reduce the local pain. 3. Surgery: Synovial hyperplasia can cause joint effusion, joint pain and limitation of movement in severe cases. After physical therapy and medication are ineffective, surgery is needed to improve the symptoms. If synovial hyperplasia occurs, it is recommended that treatment be carried out under the guidance of a doctor.
