The investigators are doing this study to better understand the role of the central nervous system in processing painful stimuli in patients with fibromyalgia. Specifically, the investigators would like to know whether the central nervous system processing of painful stimuli changes with time and with talk therapy. In addition, the investigators are investigating how changes in your fibromyalgia symptoms may affect certain markers or proteins in your blood.

Primary Outcome Measures:
  • Aim 1: Test the feasibility and subject acceptability of a potentially objective tool (NFR) for measuring pain severity. [ Time Frame: Baseline, Week 9, and Week 12 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Aim 2: Determine the longitudinal relationships of changes in patients' symptoms with changes in plasma levels of neuropeptides and NFR pain threshold. [ Time Frame: Baseline ] [ Designated as safety issue: No ]
