How does Oveallgo NerveEase Carpal Tunnel Treatment Device works? Pain related to CTS often manifests more prominently during the night-time hours, as the body is at rest and nerve repair mechanisms are activated. As a result, our NerveEase Carpal Tunnel Treatment Device is designed to be applied at night during sleep. It can not only alleviate pain but also repair damaged nerves and muscles. Our GFOUK NerveEase Carpal Tunnel Treatment Device can help in pain management by stimulating the muscles around the damaged nerve, which can, in turn, promote the release of endorphins so as to relieve the various symptoms. The GFOUK NerveEase Carpal Tunnel Treatment Device can also help reduce pain associated with arthritis by stimulating the surrounding muscles. Improved muscle strength and circulation can help improve joint support and mobility. Plus, EMS have a mild anti-inflammatory effect, which can assist in reducing localized swelling around arthritic joints.
