Brief Summary

The goal of this clinical trial is to learn if a wearable brain stimulation device called NettleEndo can reduce chronic pelvic pain and improve wellbeing in women with endometriosis. The study also aims to assess the safety and usability of the device when used at home over several months. The main questions it aims to answer are: 1. Does at-home transcranial direct current stimulation (tDCS) reduce daily pain intensity in women with endometriosis? 2. Does the device also improve mood and sleep quality? Researchers will compare two groups-one receiving active brain stimulation and one receiving a sham (placebo) stimulation-to see if the active device provides greater improvements in symptoms. Participants will: 1. Use the NettleEndo device at home for 20 minutes per session, five times per week for 12 weeks 2. Be randomly assigned to receive either real or sham stimulation through the device 3. Complete daily and weekly symptom ratings through a mobile app 4. Be followed for 90 days after completing the intervention to monitor longer-term effects All activities are completed remotely using a smartphone app. Participants can contact the study team with questions at any time. The study is double-blind, meaning neither participants nor the researchers assessing outcomes will know who received active or sham treatment until the end of the trial.
