Switching off the pain

LAKE FOREST, Ill. — Omron recently charged analgesic aisles with a new pain relief option. Omron's Electro-Therapy Pain Relief unit is the only approved transcutaneous electrical nerve stimulation unit on the market and should be an adjunctive sale for chronic pain sufferers. The product could add a spark to nonmedicinal, external pain relief. Sales of heat and ice packs were relatively flat in 2012, with sales approaching $235 million.
