What is a TENS machine?
A TENS machine delivers tiny electric shocks to the body for a natural form of pain relief. The electrical pulses interfere with the pain messages being sent to the brain, which is why it can also be an effective form of pain relief during the early stages of labour. It is not recommended that you use a TENS machine during early pregnancy and during those later months of pregnancy, you may prefer a pregnancy support belt. However, it is an excellent way of administering pain relief without the use of medications after you give birth.
You also can't use a TENS machine if you suffer from heart problems, epilepsy or have a heart pacemaker. They certainly can't be used if you're planning to have a water birth. Make sure you speak to your GP or midwife before purchasing a TENS machine to find out whether it's suitable for you.
How do you use a TENS machine for back pain?
Firstly, follow the instructions according to the model you are using to use the device properly. Generally, you will start by placing the electrode patches on clean skin at the location of the pain in your back. The patches are usually attached to the machine with wires, and depending on the type of machine, you may have to use conductive gel.
The machine will usually start pulsing at around 80Hz. If your pain sharpens, you can then increase the pulses. After some time, you may experience ‘accommodation’, which is when your body adjusts to the pain, and you can then increase the pulses again.
You can choose to use either two or four electrode pads depending on how large the area of pain is that you are tending to. If your lower back pain is on one side, try using two electrodes. Place one pad at the top point of the pain and one pad below (about one inch apart). Try to place the pads on the muscle, as opposed to directly onto your backbone.

I sussed out how to use it in five minutes. l used it twice on my terribly painful neck and shoulder and actually managed to sleep on my painful side for the first time in weeks. My husband sticks the pads on my back and shoulder area, and l keep it on all day.....turning it on at least three times during the day. So far, so good and, hopefully, this will give me some pain relief finally!"

I checked out all the TENS machines on Amazon and settled on this one as I think she would find this one the easiest to use at her age. She has reported that after using the TENS Machine her pain is nearly completely gone. Every time she feels the pain coming back to, she pops it back on to try and stop the pain before it gets too bad."

Review: "I already have a TENS machine from the same company, which works extremely well to control my severe backache. However, the wires were a nuisance at times, and when bending, the unit sometimes fell off my trouser waistband. I love my neat, wireless machine, although I find that so far, having had it for just a couple of weeks, it doesn’t remove my pain totally. However, I’m gradually moving the strength up and still have a few clicks to go. I would happily recommend this wireless TENS machine to anyone who suffers from pain."
The conductive gel will improve conductivity for best stimulation and results. These 100ml bottles can be used for use with TENS machines and can be attached to the electrodes pads when they have lost their self-adhesive properties.
How much does a TENS machine cost?
TENS machines used to be very expensive, but you can now pick one up for around £50 or less online, or at a pharmacy.
How long does pain relief last?
The duration of pain relief after using a TENS machine can vary. However, some people report that their pain returns as soon as they switch off the device. Other users state that their pain does not return for a while after, such as for 24 hours or more.
Here is a video from Ask Doctor Jo's YouTube channel on how to apply a TENS machine unit for back pain.
Do TENS machines work?
The Endorphin Release theory suggests that TENS works by sending electric current that only focuses on the sensory nerve endings that control pain. These currents that pass to the brain releases endorphins, a hormone known as the body’s natural painkiller. These endorphins act exactly like prescription drugs, but without the side effects.
TENS can be used to alleviate pain caused by a wide range of problems like back pain, joint pains, arthritis, sciatica, nerve pain, bone pain, neck pain, sports injuries, muscle pain, and even period pain. Although sometimes, it is also used during labour as a method of pain relief.
