Sciatica Pain Relief: Do Tens Machines help with Relief?

What is TENS?

 Transcutaneous Electrical Nerve Stimulation or normally known as TENS have become a widely used product for several conditions, pains or other reasons, but it is widely used amongst a mixture of age groups.


Tens machines produce a small electrical current that focuses heavily on muscle stimulation and nerves, targeting sensory nerve endings that control your pain caused by injuries and muscle spasms. This electrical current passes through your muscles and nerves and sends a message to the brain to release chemicals called endorphins to the body, the body’s natural pain killer. Whilst sending this message to the brain to release this chemical, it will also send another message to block signals to pain receptors around the affected or treated area (where the electrodes are placed).

Is a Tens Machine good for Sciatica? 

Tens Machines are fantastic machines that help with pain relief, especially sciatica. TENS can relief sciatica pain as it does other conditions – stopping radiating or even sometimes shooting pains that some customers have been known to have.

A Tens unit is a safe, non-addictive and often a tradition remedy when aiming at pain relief from sciatica. Usually when treating sciatica – most treatments are connected to drugs or regular visits to a chiropractor, sometimes customers have found themselves having to have anti-inflammatory injections before they’ve found a Tens machine that can help them.

Usually, the main causes of Sciatica pain is:

  • Cervical Spinal Stenosis – The is commonly found in those who are 50 and over.
  • Lumbar Herniated Disc – The lumbar herniated disc is when the inner layer leaks because of a rupture of some sort. The disc is the soft inner material in the spinal cord.
  • Degenerative Disk Disease – Degeneration is common with older age and in most cases can lead to inflammatory proteins leaking from the vertebrae affecting roots in the nerves.

Tens Machines relieve sciatica pain like no other machine can do. One of the major benefits when using a Tens Unit is that you will not have any side effects, compared to your other possible treatments available.


What is Sciatica?

Sciatica manifests as pain that courses along the path of the sciatic nerve, extending from the lower back, through the hips and buttocks, and down each leg. Typically, this condition arises from pressure on a segment of the nerve due to a herniated disk or bone overgrowth, resulting in inflammation, pain, and often numbness in the leg.

While the pain linked to sciatica can be intense, it usually alleviates with appropriate treatment within a few weeks. Severe cases accompanied by notable leg weakness or changes in bowel or bladder function may necessitate surgical intervention.

Termed scientifically as neuropathy of the sciatic nerve or sciatic nerve dysfunction, sciatica is frequently mistaken for general back pain. However, it transcends mere back discomfort, given the sciatic nerve's status as the body's longest and widest nerve, extending from the lower back, through the buttocks, down to just below the knee.

Back pain presents in diverse forms, appearing suddenly and briefly (acute) or persisting for extended periods (chronic). Its onset can be immediate following an injury or gradual over months, posing challenges in pinpointing the exact cause. Over-the-counter medications can offer relief for specific types of back pain, but more robust medications and surgical interventions may be necessary for others.

Key Points about Sciatica:

  • The sciatic nerve is the longest nerve in the human body.
  • A slipped (herniated) disk is the primary culprit behind sciatica.
  • Cognitive behavioral therapy can aid in managing sciatica-induced pain.


How to use a Tens Machine for Sciatica?

The first question many people ask is when using a Tens Machine for sciatica is How Often Should I Use my Tens Machine? – We usually recommend a single treatment be as little as one 30-minute session, however other customers have used it for several hours a day – it’s really the user’s preference as to how long and how many times a day they choose to use it.

That all being said, we recommend not overusing it per day – perhaps once or twice if using for a prolonged period as the body may become used to the treatment and it could work against you, or perhaps not work as well as it should.


Tens Machine placement for Sciatica (Electrodes)

Placement of your tens electrodes is key when treating sciatica with Tens Machines.

  • Lower Back Pain – Attach both pads on the lower back with the backbone in the centre of the pads. Do not place the electrodes on the backbone of the spine.
  • Hip / Thigh – Attach one pad on either side of your hip or on the area where you feel the most pain.
  • Sciatic nerve – The placement of these electrodes will be on one side of the lower back (do not place on the spine or backbone). Attach one pad below and above the region of pain, both same side.

Symptoms of Sciatica

Sciatica pain can occur along the sciatic nerve, a major nerve in your body. Typically, this discomfort starts from your lower back, travels through your buttocks, and extends down your thigh and calf. 

The pain's intensity can range from a mild, dull ache to a strong, burning, or sharp sensation. At times, it can even feel like a sudden jolt or an electric shock. Certain actions like coughing, sneezing, or prolonged sitting can exacerbate the pain. Usually, it affects one side of your body.


Common Symptoms:

  • Pain shooting along the path of the sciatic nerve, from your lower back through your buttock to your leg.
  • Numbness in your leg along the nerve.
  • A tingling sensation, akin to pins and needles, in your feet and toes.
  • Weakness in the muscles of your leg or foot.
  • Occasionally, one part of your leg may experience pain while another part feels numb.

The pain may start gradually and worsen after prolonged standing or sitting. It may intensify at specific times of the day, such as during the night. Actions like sneezing, coughing, laughing, or activities that involve bending backward or walking can also increase the pain.

Key Points to Note:

Typically, sciatica affects one side of your lower body. The pain pathway usually extends from your lower back through your thigh and down to your leg, sometimes reaching your foot or toes depending on the nerve irritation.

For some individuals, sciatica pain can be intense, hindering regular activities. However, for others, it may not last very long, yet it can be bothersome and may potentially worsen over time.

Rare Symptoms:

Sometimes, sciatica can cause rare and severe symptoms. If this happens, it's crucial to seek immediate medical help. These severe symptoms may include:

  • Loss of Control: If you suddenly can't control your bladder or bowels, especially if it happens unexpectedly, it could be a sign of a serious condition called cauda equina syndrome (CES). This needs urgent medical attention. CES can also cause sudden leg pain, weakness, and numbness in certain areas, and even affect your sexual function.
  • Worsening Nerve Symptoms: Sometimes, sciatica can cause nerve problems to get worse. These problems might affect your legs, causing numbness, tingling, weakness, or strange sensations. While these symptoms mean the sciatica is severe, surgery isn't always needed. Treatments like injections or nerve blocks can often help without surgery. It's essential to get medical advice promptly in such cases.

Alternative Treatments for Sciatica


Treatment Advice and Diagnosis
  • Sciatica is a symptom that arises from an underlying medical condition, and identifying and addressing the root cause is crucial. Frequently, it resolves on its own without requiring specific treatment. To alleviate pain and reduce inflammation, your healthcare provider may suggest the following steps:

Pain Relief: 
  • Utilize over-the-counter pain relievers such as ibuprofen (Advil, Motrin IB) or acetaminophen (Tylenol).
  • Apply cold packs for the initial 48 to 72 hours, then transition to using heat on the painful area.
  • Tens Machines for Sciatica are very popular machines, they’re not a cure but a pain relief treatment. 

Self-Care Actions:
  • Avoid bed rest, as it's not recommended.
  • Initiate gentle back exercises early to strengthen your back.
  • Gradually return to your regular activities after reducing activity for the initial few days.
  • Steer clear of heavy lifting or twisting your back during the initial 6 weeks after the onset of pain.

Physical Therapy:
  • Your provider may suggest physical therapy to address the underlying condition causing sciatica.
  • Some of these physical activities may be found in our top pain relief treatments for sciatica. 

Medical Injections:
  • Certain medicines may be recommended via injections to reduce nerve-related swelling and alleviate sharp pains caused by irritation.

Consulting Specialists:
  • If nerve pain persists, seeking advice from a physiatrist or pain specialist for a broader array of treatment options is advisable.

Alternative Methods
  • Acupuncture is a popular option, it can be a bit costly but it can very much help with relieving your pain. Some studies have suggested that acupuncture can help those with back pain, however other studies have mentioned that those suffering from sciatica found no benefit. 
  • Chiropractors could be an option - the manipulation to restore spinal movement and decrease pain. This type of treatment has been known to help those with lower back pain.

Surgery (In Extreme Situations):
  • Surgery is considered a last-resort option if the pain is severe, accompanied by weakness, or if there's a loss of bladder or bowel control. This surgical intervention involves removing bone spurs or herniated disks that are pressing on nerves.

For many individuals, self-care activities and at-home remedies like using hot or cold packs, gentle stretching, and over-the-counter pain medication help in easing sciatica. If the pain continues, medical interventions including diverse medications, physical therapy, steroid injections, acupuncture, chiropractic treatment, or in extreme cases, surgery, may be contemplated. The appropriate treatment choice is contingent on the severity and persistence of the symptoms


Home or Self Treatment
For most people, sciatica responds to self-care measures. Although resting for a day or so may provide relief, staying inactive will make symptoms worse.

Other self-care treatments that might help include:
  • Cold packs or Cold Gels: Place a cold pack or Cold Gel on the painful area for up to 20 minutes several times a day. Use an ice pack or a package of frozen peas wrapped in a clean towel.
  • Hot packs: After 2 to 3 days, apply heat to the areas that hurt. Use hot packs, a heat lamp or a heating pad on the lowest setting. For continuing pain, try using both warm and cold packs, one at a time.
  • Stretching: Stretching exercises for the low back might provide some relief. Try to hold the stretch for at least 30 seconds. Avoid jerking, bouncing or twisting during the stretch.
  • Medications: Pain relievers such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve) are sometimes helpful for sciatica. Use only as directed.
