- 9-volt batteries
- Protective carrying case
- Gel

Step 1
Purchase a TENS machine from any number of online sources or medical supply stores. Most companies require a doctor's prescription for the unit. The machine is a small battery-operated device that also comes with an AC adapter. It is about the size of a remote control, and it has electrodes that are placed on the skin over the affected area. It averages about $100.

Step 2
Order extra electrodes for future use with the same prescription so that you will have them. Electrodes are available in reusable cotton materials, lightweight forms for people with sensitive skin and non-adhesive brands. Other accessories to consider include extra lead wires, 9-volt batteries and a protective carrying case.

Step 3
Study the manual to get an understanding of the various frequencies that can be achieved with a TENS unit. Most people get the best results from the higher frequencies. Frequencies between 90 and 130 are recommended. Steady pulse widths should range between 80 and 120, though most people discover through experimentation which settings produce the best results. TENS have been proven to be safe and effective for a number of disorders, according to the National Institutes of Health.

Step 4
Place the electrodes directly on the source of the pain over a spot of gel. Most TENS units have up to four wires that can be attached with sticky adhesive pads that are built into the ends of the wires. Surround and cover the painful area with the electrodes. Attach the wires to the unit, and slowly turn on the TENS equipment.
