Summary

This study tested whether a TENS unit, a small device that sends mild electrical pulses through the skin, can reduce pain during endometriosis flares. Forty women with surgically confirmed endometriosis tracked their pain for three months without the device, then for three months while using it during flares. The goal was to see if the TENS unit lowered daily pain scores and improved quality of life.
