What is peripheral neuropathy? Does it ever go away?
Peripheral neuropathy occurs when there is direct damage to a nerve outside the brain and spinal cord. The warning signs include numbness, burning, stabbing pain and tingling in the hands and feet. However, it can also affect the sciatic nerve, or nerves in the neck and shoulder. Sciatica, carpal tunnel syndrome, neck radiculopathy and thoracic outlet syndrome are all common types of peripheral neuropathies, and many people with disc bulges or pinched nerves in their neck or back can also go on to develop this kind of injury.
The pain in peripheral neuropathy is a specific type of pain, that can feel like sharp stabbing pain or an intense dull ache. Often, there is also numbness, pins and needles, burning, or muscle weakness and paralysis. Sometimes it feels like you’re wearing gloves or socks when you’re not, and even the slightest touch, such as the feeling of bedsheets against the skin, can feel excruciating. It can also disrupt digestion, circulation, blood pressure or urination, as well as balance, gait, and movement coordination.
Anyone can develop peripheral neuropathy, however it is particularly common in people with autoimmune disease, diabetes, post-chemo, or after shingles. It affects nearly 50% of adults with diabetes during their lifetime, and can lead to foot ulcers in up to 50% of cases . It can also affect up to 70% of people after chemotherapy treatment . In people undergoing chemotherapy, light therapy has also been shown to be effective in treating associated lymphoedema, pain, dermatitis, and jaw issues .
Peripheral neuropathy significantly impacts quality of life, not just due to the intense pain, but also the increased difficulty walking and moving, as well as the other effects on movement, sensation and body function. In extreme cases when not treated effectively, the destruction of the nerves is so great it can lead to amputation.
Medication for peripheral neuropathy is unfortunately not very effective, and many people still experience intense pain, or experience serious side effects - the pain never goes away completely. The medication commonly prescribed for neuropathic pain can also be highly addictive, with strong withdrawal symptoms, as well as side effects such as dizziness and drowsiness (inability to drive safely), as well as weight gain and changes in appetite.
How does light therapy help Peripheral Neuropathy?
Light therapy is a natural, painless therapy that’s shown to be effective in treating peripheral neuropathy [3-5]. Red light therapy and infrared laser light used at very specific doses and wavelengths has been shown to modulate pain signals from injured nerves, as well as promote healing and repair by improving blood flow and circulation through nitric oxide release. It also triggers a whole cascade of reactive oxygen species (ROS), and regulates the influx of intra-cellular calcium, both which are fundamental for nerve growth and repair. In this way, linfrared and red ight therapy has been shown to stimulate neurogenesis, which is the growth of new healthy nerve cells, as well as be neuroprotective against future nerve damage.
Which SYMBYX light therapy treatment best helps Peripheral Neuropathy?
Given nerves can take a long time to heal, having a light therapy device that is drug-free, effective, painless, and applied from the comfort of your own home is extremely useful. The SYMBYX Biome DermaCare and DuoCare 904 devices are both medically approved laser light therapy devices available for home-use. Both devices can be used to reduce pain and inflammation, as well as improve tissue repair. The DermaCare uses red light therapy at the wavelength of 635 nm, which is effective for treating peripheral neuropathy of the hands and feet. However, for deeper chronic pain issues, such as Sciatica or sciatic nerve pain, the DuoCare 904 may be recommended. This is because it uses infrared light therapy, at 904 nm, which penetrates deeper into the body.
If you are unsure which device is best for you, our international Clinical Support team are available to provide ongoing support and guidance by phone or video chat. They are well-versed in treating people with peripheral neuropathy, and you can contact them or set up a time to speak via email to email@example.com.
To purchase please visit DermaCare or DuoCare 904 product pages. All our laser and light therapy devices come with free international shipping, warranty and worldwide Clinical Support via phone or video.
