Answer: Still's disease is a rare form of inflammatory arthritis that can cause a range of symptoms, including high fever, rash, and joint pain. Treatment typically involves the use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, naproxen, or indomethacin to reduce inflammation and pain. Corticosteroids such as prednisone may also be used to reduce inflammation and suppress the body's immune system. Disease-modifying antirheumatic drugs (DMARDs) are often used to slow the progression of Still's disease and prevent joint damage. DMARDs include medications such as methotrexate, hydroxychloroquine, sulfasalazine, and leflunomide. Additionally, biologic response modifiers such as etanercept, adalimumab, and infliximab may be prescribed. Finally, physical therapy and exercise are recommended to help strengthen the muscles, increase mobility, and reduce pain.
