Patient's question:
The child is only 12 years old, and their health has always been good. Recently, though, they have been complaining of pain here and there. Sometimes, when they go outside for a walk, they say their knee joints hurt after walking for a while. Other times, they don’t do much—they just go to school normally, and when they come back, they say their arms hurt and feel sore. I’m very worried that this young child might have something like rheumatoid arthritis or rheumatoid joint pain.Doctor's answer:
Children can also get rheumatoid arthritis. Juvenile idiopathic arthritis (JIA) is a common connective tissue disease in children. JIA differs from adult rheumatoid arthritis in many ways. Its characteristics include not only joint inflammation and deformities but also often prominent systemic symptoms, such as fever, rash, hepatosplenomegaly, lymphadenopathy, pleuritis, and pericarditis. Younger children often first present with persistent, irregular fever, and their systemic symptoms are usually more pronounced than their joint symptoms. Many studies suggest that this disease is related to immunity, infection, and genetic factors, but the exact cause and pathogenesis have not yet been fully determined.
