This Week - T : TENS (TE Nerve Stimulation)

What TENS is for

TENS can help relieve certain types of short-term and long-term pain such as:

period pain
labour pain in pregnancy
pain caused by a sports injury
pain caused by a condition like arthritis or endometriosis

It's thought to work by encouraging your body to release natural painkillers called endorphins and by stopping pain messages from your nerves reaching your brain.

TENS does not work for everyone.

If you're not sure what's causing your pain, see a healthcare professional before using a TENS machine.

Important

Do not use TENS if:

you have epilepsy
you have a pacemaker
