A) The primary aim of this study is to determine whether transcranial direct current stimulation applied to the motor cortex in patients with chronic pelvic pain induces a significant decrease in the pain or symptoms as compared with sham tDCS. We will also measure changes in the clinical symptom scores of multiple pelvic organs, drug intake (narcotic), anxiety, depression, traumatic stress, as well as overall improvement in the quality of life to assess the effects of this treatment.
