AccuRelief TENS Unit Muscle Stimulator Pain Relief System

1. Introduction

The AccuRelief TENS Unit Muscle Stimulator Pain Relief System is designed to provide temporary relief of pain associated with sore and aching muscles in the neck, shoulder, back, arm, leg, and foot due to strain from exercise or normal household and work activities. TENS (Transcutaneous Electrical Nerve Stimulation) therapy works by sending stimulating pulses through the skin to the nerves, which helps to block pain signals and encourage the body's natural pain relief mechanisms.
