The goal of this observational study is to learn about spatial and temporal nociceptive filtering in adolescents with chronic overlapping pain conditions (COPCs). The main questions it aims to answer are:
1. If spatial and temporal filtering of nociceptive information is disrupted in youth with COPCs compared with youth with localized pain conditions and healthy controls. 2. If disrupted nociceptive processing at baseline is associated with the transition from a single localized pain condition to COPCs in youth.
Participation includes:
