A transcutaneous electrical nerve stimulator (TENS) sends electrical pulses through the skin to start your body’s own pain killers. The electrical pulses can release endorphins and other substances to stop pain signals in the brain.
What is TENS used for?
A TENS may be used to help with many types of chronic (long-term) pain, such as:
Do not use TENS if you have:
- Arthritis or other joint pain
- Back and neck pain
- Muscle pain
- Neuropathic pain
Talk with your health care provider if you have:
- A cardiac pacemaker or defibrillator
- Spinal cord stimulator
- In-dwelling pumps or monitors
