Shock away the cramps: tiny TENS patch tested for period pain

This study tested a portable TENS device—a small patch that sends gentle electrical pulses—to see if it can reduce menstrual pain in women with primary dysmenorrhea (painful periods without an underlying condition). Thirty-four women used the device on their lower belly during pain episodes for about 20 minutes, over up to three menstrual cycles. The goal was to measure pain relief, quality of life, and mood changes, offering a drug-free option for managing period pain.
