Can TENS machines be used by everybody?

TENS machines tend mainly to be used to help reduce pain from problems in muscles, joints and nerves (so-called musculoskeletal pain). They may work better for these problems than for tummy (abdominal), chest or head pains. Unlike a lot of medication there are virtually no side-effects when using a TENS machine. However, people with the following must not use a TENS machine:

When the cause of the pain is not known or is not diagnosed.

1.Pregnancy (unless specifically medically advised - or in labour).

2.Pacemakers.

3.Epilepsy or certain types of heart disease.
