A transcutaneous electrical nerve stimulation (TENS) unit is the most common nerve stimulator that is purchased. It treats many conditions, including low-back pain, arthritis, headaches and joint pain. The unit works by sending electrical impulses to your nerves while blocking pain signals from reaching your brain. TENS units can be purchased with or without a prescription, and many places sell them.
You can, of course, get this piece of equipment through your doctor. He can provide one for you or write a prescription for one so that you can pick up a TENS at your local medical supply store. With this way, you can ask your medical insurance to pay for the unit.
