Healthcare Use Patterns and Economic Burden of Chronic Musculoskeletal Pain in Children before Diagnosis.

Objectives: To evaluate the healthcare use and costs of amplified musculoskeletal pain syndrome (AMPS) in children before diagnosis.

Study Design: We performed a retrospective study in children with AMPS at a pediatric rheumatology clinic between 2010 and 2014. Data were abstracted on 80 patients after primary rheumatic diseases were excluded.
