Transcutaneous electrical nerve stimulation is an unproven way to reduce body pain, though many people swear by it. TENS devices are small battery powered units that have two electrodes that you stick onto your skin. According to WebMD,

When the current is delivered, some people experience less pain. This may be because the electricity from the electrodes stimulates the nerves in an affected area and sends signals to the brain that block or "scramble" normal pain signals. Another theory is that the electrical stimulation of the nerves may help the body to produce natural painkillers called endorphins, which may block the perception of pain.
