Treatment
Arm Description
Control subjects undergo a skin biopsy.
Subjects in the treatment arm also undergo a skin biopsy, followed by 8 week treatment with Duloxetine.
Outcomes
Primary Outcome Measures
Pain Reduction
Changes in Pain measured by Numeric Pain Rating Scale over time. The Numeric Pain Rating Scale (NPRS) is assessing the patients pain on a 11-point rating scale from 0 - 10 with 0 being no pain at all and 10 being the worst imaginable pain. The test is self-reported and can also be administered by an interviewer.

5. Study Description
Brief Summary
Subjects with Fibromyalgia who respond to Duloxetine have specific nerve fiber characteristics. This can be used to predict which future patients will respond to Duloxetine.
Detailed Description
Subjects will have skin biopsies taken and evaluated for specific pathologies. All subjects will undergo a treatment period with Duloxetine. The analysis will correlate treatment effectiveness with pathological skin biopsy findings to predict future treatment success.
