Patients with bone and joint issues experience joint swelling, which may be attributed to osteoarthritis accompanied by damage to the synovium, leading to synovitis and hence the swelling. Treatment for this condition should begin with rest. Individuals who are overweight should consider losing weight. Treatments can include hot packs, physical therapy, anti-inflammatory and analgesic medications, drugs that nourish cartilage, and medications that improve blood circulation and remove blood stasis to aid recovery. Minor swelling or fluid accumulation can gradually be absorbed through these measures. In cases of significant fluid accumulation, surgery may be necessary. For the treatment of osteoarthritis, it is advised to visit an orthopedic clinic for comprehensive examinations like X-rays, CT scans, etc., and undergo standardized treatment. (Please use specific medications only under the guidance of a doctor, and do not medicate on your own.)
