Have you ever experienced a sharp, shooting pain that travels down your arm or leg? Or perhaps a persistent tingling, numbness, or burning sensation that just won't go away? If so, your nerves might be why, and a technique called nerve flossing could help.
At Renew Wellness, we believe in educating our patients about the treatments we use and how they help. So, we're breaking down everything you need to know about nerve flossing: what it is, how it works, and if it might be right for you!
Nerve flossing is a physiotherapy technique used to free nerves that have become restricted, compressed, or "stuck" within surrounding tissues.
Just like a piece of floss moving back and forth between your teeth, nerve flossing involves carefully mobilizing the nerve so it can glide smoothly through the muscles, tendons, and other structures it passes through. The goal is to restore the nerve's natural movement and reduce pain, tingling, or discomfort.
Your peripheral nerves (the ones that branch out from your spinal cord to your limbs) are designed to move and glide as your body moves. When you reach overhead, bend forward, or extend your leg, your nerves are constantly stretching and sliding through tight spaces between muscles, bones, and connective tissue.
Nerves can become restricted or irritated due to:
When a nerve gets "stuck," it loses its ability to glide freely. This can cause pain, numbness, weakness, or that classic pins-and-needles sensation many people know all too well.
Nerve flossing works by gently tensioning and releasing the nerve from both ends, encouraging it to slide through the surrounding tissue. Think of it like feeding a rope through a narrow pipe: if the rope gets caught, you gently wiggle it through rather than yanking it.
There are two main types of nerve mobilization techniques:
This technique involves moving the nerve in one direction while simultaneously releasing tension from the other end. This creates a gentle "sliding" motion without placing too much tension on the nerve at once. Sliders are often used in early stages of treatment or when the nerve is particularly sensitive.
This technique places the nerve under mild tension from both ends simultaneously, helping to stretch and mobilize it more aggressively. Tensioners are typically used once the nerve has calmed down and can tolerate more load.
Your physiotherapist will determine which technique is most appropriate based on your condition, symptoms, and stage of recovery.
Nerve flossing is used to treat a wide range of conditions, including:
| Condition | Nerve Affected |
|---|---|
| Sciatica | Sciatic nerve |
| Carpal Tunnel Syndrome | Median nerve |
| Tennis Elbow (Neurogenic) | Radial nerve |
| Thoracic Outlet Syndrome | Brachial plexus |
| Piriformis Syndrome | Sciatic nerve |
| Cervical Radiculopathy | Cervical nerve roots |
| Plantar Fasciitis (Neurogenic) | Tibial nerve |
| Cubital Tunnel Syndrome | Ulnar nerve |
When performed correctly, either by a trained physiotherapist or following proper guidance, nerve flossing is generally very safe. However, it's important to note:
Once cleared by your physiotherapist, here's a basic sciatic nerve floss exercise you can try:

You may feel a gentle pulling sensation down the back of your leg, and that's normal. Stop immediately if you feel sharp or severe pain.
If you're experiencing any of the following, it's time to book an appointment:
Nerve flossing is a powerful yet gentle technique that can make a real difference for people suffering from nerve-related pain and dysfunction. When incorporated into a comprehensive physiotherapy treatment plan, it can help restore normal nerve movement, reduce pain, and get you back to doing the things you love.
