Paingone is a convenient and easy-to-use pen-shaped device designed for pain management. It operates on the TENS principle (transcutaneous electrical nerve stimulation), but unlike conventional TENS devices, the Paingone device does not require any wires, electrodes, or batteries. This allows the Paingone pen to be used anytime and anywhere. The main part of the device is directed straight to the painful area, or pain can be treated from an acupuncture point. The battery-operated device works automatically by pressing the power button.

Paingone operates using low-frequency electrical charges produced by piezoelectric crystals, enabling long-lasting and clinically proven pain relief. It sends electrical impulses that activate the nerve pathways. As a result of the treatment, the brain produces the body's own pain-relief hormones, endorphins, transmitted through the spinal cord, which eliminate the sensation of pain.
