Outcome Measures

Primary Outcomes (1)

  • Change in Brain Gray Matter Volume

    The change in gray matter volume is evaluated by subtracting the volume after the treatment (week 16) to the volume before treatment (baseline)

    16 weeks compared to baseline

Secondary Outcomes (1)

  • Change in Pain Magnitude

    16 weeks compared to baseline

Study Arms (2)

Duloxetine

EXPERIMENTAL

Duloxetine capsule 30mg once a day for one week, then 60mg once a day for 15 weeks, then 30mg once a day for one week.

Drug: Duloxetine

Sugar pill

PLACEBO COMPARATOR

Matching capsule given once a day for a total of 17 weeks.

Drug: Sugar pill

Interventions
