Move again with targeted sciatic nerve pain relief using our TENS machine

Do you suffer with shooting pain that makes it hard to get out of bed and go about your day? Frustrated by needing to rely on other people because you’re in too much pain to move? Neuropathic pain is usually chronic pain and severe and can be hard to treat. It is usually caused by damage, disease or injury to nerves in the body. Common types of neuropathic pain include peripheral neuropathy, diabetic neuropathy, post-herpetic neuralgia (a complication from shingles).

Sciatica is a type of neuropathic pain that causes shooting pain down the sciatic nerve, extending from the back down the legs. About 5 to 10% of people with low back pain have sciatica. Sciatica often goes away within a few months but sciatic pain relief is often needed. If not treated, sciatica can get even more painful due to permanent nerve damage and it can become even harder to move around. Some people even lose control of their bladder because the sciatica damaged their spinal cord.

A TENS machine can provide relief from sciatic pain and improve mobility while you recover.


Is a TENS Machine Good for Sciatic Nerve Pain?

Physiotherapists often use a TENS machine to help provide sciatic nerve pain relief. The TENS unit sends non-painful electrical pulses across the skin and along nerves to the brain to provide drug-free pain relief. The electrical stimulation helps the body to produce endorphins, a natural pain killer.

TENS is effective in relieving pain by acting on both the central and peripheral nervous system (Hashmi, Shaik, Kumar & Pillai, 2015). It floods the brain with endorphins, making sciatica patients feel less pain.

How to Relieve Sciatic Nerve Pain Using TENS Machine?

Using a TENS machine for sciatic treatment is as effortless as applying the electrodes to the correct body locations. People can turn on the machine and let it run for about 30 minutes. The treatment duration depends on the patient’s preferences.  Sciatic nerve pain . It is wise to understand that TENS-related sciatic nerve pain relief only lasts about three to four hours.

In general, the device comes with adjustable settings, allowing patients to modify the pulse rate to ease the pain. It is not unusual for first-time users to feel strange because the TENS machine produces a tingling sensation. Generally, the following settings are recommended for optimal results:

  • Pulse Rate: 2 to 10Hz for chronic Sciatic pain
  • Pulse Rate: 80 to 120Hz for acute Sciatic pain
  • Pulse Width: 175 - 200 us

Where Do You Put TENS Pads for Sciatic Nerve Pain?

The effectiveness of TENS for sciatic nerve pain depends on accurate electrode placement. The electrodes are self-adhesive, ensuring more convenient application on the lower back.

Sciatic nerves branch out from the L4 level in the lower back area through the buttocks and hips and down to the legs [1]. The best way to place the TENS pads for sciatic nerve pain relief is to apply one TENS electrode directly over L4 level and a second pad below the belt line on the booty area. And repeat the same position for the second channel. This orientation allows for a more efficient flow of electrical stimulus.

Alternatively, if you have piriformis syndrome, one can place one electrode pad below the belt line on the booty area, and the other one on the back of the legs. Please refer to the picture below for help.

Benefits of Using a TENS Machine for Sciatic Pain Relief

Transcutaneous electrical nerve stimulation provides numerous benefits, including the following.

  • Effective pain relief
  • The TENS machine delivers effective sciatic nerve pain relief by promoting the release of naturally occurring endogenous strong-pain-relief-like substances [1] from the brain. These substances block the pain pathways while giving patients the mobility immediately.

  • Non-invasive
  • Sciatic nerve pain Australia therapies require no needles to puncture the skin and create a potential entry point for microorganisms. Itonly needs the application of self-adhesive pads on the skin. 

  • Drug-free and No side effects
  • Unlike pharmacologic treatments for sciatic nerve pain relief (i.e., nonsteroidal anti-inflammatory drugs, corticosteroids, antidepressants, muscle relaxants, opioid analgesics, and anticonvulsants), TENS has no side effects.

  • Treatment on the go
  • A TENS machine is portable enough to carry in one’s bag, allowing people to relieve sciatica pain wherever they are.

What Causes Sciatic Nerve Pain?

Sciatic nerve pain can be due to many reasons [1], including the following.

  • Slipped or Herniated Disk 
  • The spine consists of 33 spinal bones or vertebrae. Spinal discs sandwich each bone to protect it against impact forces and vibrations. Excessive pressure between two adjacent vertebrae can cause the disk’s gel-like center to bulge outwards. In some cases, a spinal disk slips out of its anatomical position. Either can compress the sciatic nerve.

  • Degenerative Disk Disease
  • The spinal disk can deteriorate over time, narrowing the spinal nerve passageway (spinal stenosis) and pinching the sciatic nerve roots leaving the spinal column.

  • Other Medical Conditions
  • Traumatic injuries and tumors in the lower spine can compress the sciatic nerve. Tightening or involuntary spasms of the piriformis muscle deep in the buttocks can also irritate the nerve, producing pain. People with cauda equina syndrome, spondylolisthesis, and osteoarthritisn can also experience sciatica.




Product Questions


What is a TENS machine?

A TENS machine is a simple electronic device that delivers a predetermined amount of electricity through the skin. It consists of a control module and cables connected to two TENS pads or electrodes. The gadget is small enough to fit in one’s pocket or bag. Most devices have at least three mode settings, including “modulation” (to limit nerve adaptation), “burst” (for chronic sciatic nerve pain relief), and “normal” (for acute pain relief).


How does TENS machine work?

A transcutaneous electrical stimulation machine, also called TENS Machine, works by delivering predetermined electrical signals through the skin. These impulses reach the nerve endings and reduce the pain impulses moving from the peripheries to the spinal cord and all the way to the brain. It also induces muscle relaxation, improving the comfort level of the person with sciatica.

The electrical signals or impulses also travel to the brain through the spinal cord, stimulating it to increase the production and release of natural opioid-like substances called “endorphins.”

Like strong pain relief drug and other opioids, endorphins block the pain pathway to relieve pain. Moreover, these substances produce euphoric effects, allowing the person to replace the discomfort with more pleasant experiences.


Who cannot use TENS machine?

Although TENS is safe and effective for pain management and muscle relaxation, it is not for everyone. For example, people with pacemakers, similar devices, or metallic implants should not use a TENS machine. People must realize that this device delivers an electrical signal to the body. Even though the electricity does not cause harm, it might adversely impact or interfere with a pacemaker’s function or other implanted medical devices in the human body.

People with epilepsy, seizure disorder, or heart problems should also not use a TENS machine to manage sciatic nerve pain. The electrical stimulation might trigger a seizure event in susceptible people. On the other hand, the heart relies on electrical stimulation from the Sino-Atrial Node to pump normally. Introducing electricity into the body might cause the heart to produce erratic heartbeats. 

Pregnant women in the first two trimesters and people with overactive bladders should also consider other sciatic treatment options.


What are the adverse side effects of TENS machine?

Transcutaneous electrical stimulation is relatively safe. Besides the tingling sensation one gets from delivering electrical signals from the device to the skin, TENS does not produce any adverse side effects.

However, some people might be hypersensitive to the TENS pads. People with allergies might develop redness, itching, and irritation on the skin covered by the TENS electrodes. 

Some patients might find a pricking or buzzing sensation during a TENS treatment session. Although these symptoms are nothing serious, they can be uncomfortable for some.

People must avoid placing the TENS electrodes over the eyes and neck because the low-voltage electricity might increase intraocular pressure or lower blood pressure.
