The primary outcome will be to identify how the presence of chronic pain changes overtime with GHT through the use of surveys, quantitative sensory testing (QST), brain MRIs, and qualitative interviews. Following recruitment and consent, participants will complete baseline survey measures and will repeat those measures at 1 months, 3 month, 6 months, and 12 months. QST measures, brain MRIs, and Qualitative Interviews will be offered to participants in cohort (1) and will be completed at baseline and 12 months.
