Trial Parameters
Brief Summary
The goal of this basic science study is to learn about the brain mechanisms of chronic pain across different chronic pain syndromes in pediatric patients. The main questions it aims to answer are: * Are there shared and distinct brain systems engaged by different forms of pediatric chronic pain? * What are predictors of recovery from chronic pain? * What brain systems are associated with the spread of pain? For this study participants will undergo: * Functional Magnetic Resonance Imaging (fMRI) * Quantitative Sensory Testing * Psychological Assessments
