Could a headset at home replace hospital visits for chronic pain?

This study tests a safe, home-use device that sends mild electrical current to the brain (tDCS) to help people with long-term pain who only got short-term relief from a similar hospital treatment. About 70 adults with chronic nerve or pain-sensitization pain will use the device 20 minutes a day, 5 days a week for 3 months. Half will get real stimulation, half a sham, and neither they nor their doctors will know which. The goal is to see if home tDCS can provide lasting pain relief and improve quality of life.
