Will a TENS machine help with Sciatica?

I want to start off with directly answering this question for those that do not have the time to read how a TENS machine can help. So will a TENS machine help with Sciatica pain? The quick answer to this question is yes, a TENS machine will help with relief of sciatica symptoms. However a TENS machine will not directly treat sciatica. The aim of using a TENS machine in sciatica treatment is to reduce the pain signals that are received in the brain, allowing you to get on with your life.

Please read on to see exactly how and why a TENS machine is able to provide you with this sciatica pain relief.

What is Sciatica?

Sciatica is a condition caused by the irritation of the Sciatic nerve. The Sciatic nerve runs all the way from your hips and down to your feet. There are many different reasons why your Sciatic nerve could become irritated or inflamed. By far the most common cause is patients who are suffering from a slipped disk in their back. When the herniated disk moves it can place pressure on the Sciatic nerve which causes the irritation.

In most cases Sciatica will clear up on its own accord in 4 to 6 weeks although in some cases it can last a lot longer. Whilst suffering from Sciatica patients can feel a number of pains and sensations in the lower body, these include but are not limited to:

The most common symptoms of Sciatica.

• Pain in the form of sharp stabbing, burning or even shooting throughout the legs and bottom.
• A tingling feeling just like pins and needles.
• A feeling of weakness in the legs and feet or other affected areas.
• There may be a sense of numbness in the legs, feet and bottom areas.
• Pain in the lower back and hip.
• A very strong shooting pain up the legs that can make it difficult to stand.

This list is not exhaustive and there can be a number of other symptoms. However these are the most common and most Sciatica sufferers will have experienced them at some point in time.

Treating Sciatica with a TENS Machine.

Even though there are many different exercises and techniques to help ease the discomfort caused by Sciatica it can still be pretty awful for the sufferer.

Modern advances in technology now mean we can help treat and alleviate the symptoms of Sciatica by using a TENS Machine. A TENS machine helps by sending small but continuous pulses of electricity through small electrodes placed on your skin.

The pulses of electricity then make their way through your skin and into the Sciatic nerve branches and endings.

This in turn causes two processes to take place:

The first process is that the body responds to the pulses by releasing Endorphins into the bloodstream. Endorphins are the bodies natural painkiller and as such work to then take the edge of the pain away.
The second phase is that the pulses actually interfere with the Sciatic nerve and its branches. What this means is that it can block and redirect the pain signals that are trying to enter the nervous system, in turn this can reduce or stop the symptoms of your Sciatica.
One of the main benefits of TENS machine treatment for Sciatica is that it can be administered anywhere and anytime that it is needed. Most of the newer machines are very small and discreet and can be placed in your pocket. TENS units can provide a safe and non addictive alternative to the usual techniques, bringing reduced discomfort and mobility to Sciatica sufferers.

The benefits of using a TENS machine to treat Sciatica.

Using a TENS machine to treat Sciatica has many benefits over conventional methods. One of the biggest benefits is that it provides natural drug free pain relief to the sufferer.

In this day and age many people are trying to keep away from over the counter and prescription medication. There are nasty and harsh side effects and not to mention the addictive nature of these chemicals. By using a TENS machine you are getting a natural relief from your Sciatica pain.

TENS machine are also very cost effective as well. Decent units can now be bought for a great price and once the initial outlay is paid it will last you a very long time. It can also be used to help treat a number of other aches and pains you or your family may feel in the future.

How to use a TENS Machine to treat Sciatica symptoms.

Using a TENS Machine for Sciatica relief couldn’t be any more easy. Most cases of Sciatica pains radiate out from the lower back area so we place the sticky pad electrodes there and along the Sciatic nerve. The diagram below shows you the exact areas to place your TENS machine electrodes to treat Sciatica. Modern TENS units feature advanced self-adhesive, pre-gelled electrode pads, making the process completely clean and mess-free. Just ensure your skin is clean, dry, and free of oils or lotions before applying the pads to guarantee a strong connection.

Once you have placed the electrodes in the correct place as shown in the example above you can turn on the TENS Machine.

It is now simply a case of choosing a mode and setting the strength and frequency. Turn up the frequency and power until it has reached a point where your pain has decreased or stopped altogether. You should find that you will not need to use any more than 50-75% of the power available. It really is as simple as that and allows you to carry on your life as you did before.

They remain highly portable and come equipped with robust, built-in rechargeable power cells.

3. Advanced Quad-Channel TENS & EMS Units (Premium Option)

For individuals suffering from severe or chronic sciatica that radiates down the entire length of the leg, an advanced quad-channel device is highly recommended. While it represents a slightly higher investment, a premium quad-channel unit provides maximum therapeutic coverage.
