NORWALK - A Norwalk man says a medication-free treatment is finally spelling relief after four years of shoulder and neck pain.

Eddie De Vingo, 55, says he had been taking pain medication regularly to keep up with his roofing business and Brazilian Jiu-Jitsu training. De Vingo says he wanted to stop taking medication that could cause side effects like liver damage.

He now receives treatment through a transcutaneous electrical nerve stimulator unit, which is a device designed to eliminate or reduce his pain by exercising muscles via the nerve.

Doctors say insurance will often cover all or some of the cost of TENS therapy. However, they emphasize that this treatment doesn't work for everyone.

The American Academy of Neurology says there are mixed study findings on its effectiveness in treating pain.
