How to Use Zewa TENS 502s

Tens of millions of Americans suffer from chronic pain that can range from mild to incapacitating. As well as affecting emotional and physical well-being, constant pain can interfere with normal daily activities. Although drug treatments are often available, many people prefer noninvasive therapy. Transcutaneous electrical nerve stimulation, otherwise known as TENS, uses low-voltage electrical current to provide pain relief. Electrodes are placed on the skin near the area of pain, and the charge is delivered by a small battery pack. The aim is to stimulate the nerves and block the pain messages that are sent to the brain. For many people, a course of TENS therapy can help them reduce the level of pain they suffer and regain some control over their lives.
