Question
The child has leg pain and a significantly high C-reactive protein index, which has persisted for 10 days. Initially, it was suspected to be growth pain, but the symptoms include loss of appetite, poor mental state, and a noticeable weight loss. Has the pain improved after intravenous treatment?
Answer
C-reactive protein is an indicator of inflammation. If a child’s leg pain is arthritis and is accompanied by elevated C-reactive protein levels, and if symptomatic anti-inflammatory treatment is ineffective, it is necessary to consider the possibility of juvenile idiopathic arthritis. For a more accurate diagnosis, more detailed information about the condition is needed, such as whether the pain is joint pain or muscle pain, and if it is joint pain, which specific joint is affected and whether both sides are painful. This information is crucial for diagnosing the condition.
