Real tDCS
Those receiving experimental treatment will receive real tDCS during 20-minute periods over the course of 10 sessions. The treatment will be delivered by trained clinical personnel.
tDCS: Prior to initiating the real tDCS trial and to reduce the likelihood of irritation associated with electrical stimulation, a low dose (1/8 of an inch) topical lidocaine (4%) cream will be applied to the skin where the tDCS the sponge-coated, surface electrodes soaked in saline solution will be placed. Neurotargeting tDCS-explorer software, Version 2.3 will be used to locate the left and right DLPFC, where anodal stimulation of the left DLPFC and cathodal stimulation of the right DLPFC will be received. Real tDCS will be applied during 20-minute periods over the course of 10 sessions. After each session, vitamin-E will be applied to the skin where the electrodes had been placed to reduce likelihood of skin irritation.

Sham tDCS
Those receiving sham tDCS will receive active tDCS during 20-minute periods over the course of 10 sessions. The treatment will be delivered by trained clinical personnel.
Sham tDCS: Participants randomized to sham tDCS will undergo the same procedures as those in the real tDCS sample, including the same pre-treatment lidocaine 4% cream, localization of electrode placement, actual placement of electrodes, turning on the tDCS device in sham setting but will not receive actual stimulation during the 20 minutes of each session, as well as post-treatment vitamin E.

PRIMARY outcome
Timeframe: On a weekly basis: 1) Day 1 (first day of tDCS). 2) Day 8 (after first week with post 5 consecutive sessions of tDCS followed by 2 consecutive days without tDCS). 3) Day 15 (after second week post another 5 sessions of tDCS followed by 2 consecutive daysPopulation: Analyses were not performed. Given the premature termination of the clinical program, the limited sample size of participants completing the study, the heterogeneity of chronic pain etiology and psychiatric comorbidity among participants, as well as variable and personalized interventions delivered as a part of the clinical care participants received, the data collected would have been grossly underpowered to provide meaningful results.
