TENS Dual Channel Units - a transcutaneous electro-nerve stimulator (T.E.N.S.); pain control that goes where you do. It is a small medical device slightly larger than a beeper, attaches to your pants or belt and helps alleviate pain while you wear it.

This is the best-valued, durable, medical quality, full-featured TENS Unit we have seen on the market. It is dual channeled, multi-modal and fully adjustable.

These are the good medical quality analog units that really work. The digital versions available today have pretty neat electronics, but usually don't compare in actual therapeutic value to this unit.
