If you're thinking about trying TENS, it's a good idea to speak to your GP about a referral to a physiotherapist or pain clinic.
A physiotherapist or pain specialist may be able to loan you a TENS machine for a short period if they think it could help.
You can choose to buy your own TENS machine without getting medical advice, but it's generally better to have a proper assessment first, so you can find out whether a TENS machine is appropriate for you and be taught how to use it properly.
To get the most benefit from TENS, it's important that the settings are adjusted correctly for you and your individual condition.
The information below is a general guide on how to use a TENS machine. You should always follow the manufacturer's specific instructions.
TENS machines are small and lightweight, so you can use them while you're working or on the move. You can put it in your pocket, clip it to your belt or hold it in your hand.
You can use TENS throughout the day for as long as you like, although it shouldn't be used while you're driving, operating machinery, or in the bath or shower.
Make sure the machine is switched off before you attach the pads to your skin. Position the pads either side of the painful area, at least 2.5cm (1 inch) apart.
Never place the pads over:
Turn on the TENS machine when the pads are attached in the correct places. You'll feel a slight tingling sensation pass through your skin.
The machine has a dial that allows you to control the strength of the electrical impulses.
Start on a low setting and gradually increase it until the sensation feels strong but comfortable. If the tingling sensation starts to feel painful or uncomfortable, reduce it slightly.
Switch the TENS machine off after you've finished using it and remove the electrodes from your skin.
The value must be greater than or equal to 1.
