Neurobiological Mechanisms of Stress in Youth With Chronic Widespread Pain

Participants will undergo a one hour fMRI scan with pain-induction using heat-based QST protocol.

All participants will be asked to provide saliva samples to measure cortisol response over time and dehydroepiandrosterone (DHEA) in addition to physiological measurements such as blood pressure/pulse, height/weight, and waist-hip ratio. Measurements will be taken at baseline and 4-month follow-up.
