Non-pharmacological pain relief treatments are ways to decrease pain and may be used as an alternative to or in conjunction with medicines. Electrical and magnetic pain relief devices can help reduce and in some cases alleviate symptoms, but each person may respond to these therapies differently.
A transcutaneous electrical nerve stimulation (TENS) unit is a portable, pocket-sized, battery-powered device that attaches to your skin. It is usually placed over the area of pain. It uses mild, safe electrical signals to help control pain.
If in doubt medical advice should be sort from a health care professional.
