This is a single blind, randomized controlled pilot trial of transcranial direct stimulation (tDCS) intervention or tDCS sham administered with a standardized guided imagery intervention. Up to 25 adult women with chronic pelvic pain will be enrolled and randomized (like a flip of the coin) to achieve a total sample size of 20 women. 10 women in one arm of the study will receive guided imagery with tDCS stimulation. 10 women in the other arm of the study will receive guided imagery with sham tDCS. Subjects will remain blinded until the end of the study.
