Movement is often the body’s natural response to discomfort, but nerve pain requires careful handling. Nerve pain, medically termed neuropathic or radicular pain, is a complex issue causing intense, often debilitating symptoms. Whether gentle movement or stretching provides relief depends entirely on the specific mechanical nature of the nerve. For certain types of nerve irritation, a therapeutic movement strategy known as neural gliding offers a promising path to reducing symptoms.
Understanding Nerve Pain
Nerve pain is fundamentally different from the aches and stiffness associated with muscle or joint injuries. Musculoskeletal pain, such as a pulled muscle, is localized, throbbing, or aching, and often resolves with rest and time. Pain originating from a nerve is frequently described with distinct sensory qualities like burning, shooting, electric shocks, or deep tingling. This type of pain often travels along the path of a nerve, such as from the lower back down the leg in the case of sciatica, which is known as radicular pain.
The underlying cause of this hypersensitivity is usually mechanical irritation. Nerves are meant to slide and move freely within the body’s tissues and tunnels as we change position. Problems arise when a nerve is compressed, inflamed, or develops minor adhesions that “tether” or stick it to adjacent tissue. This tethering prevents the nerve from smoothly adjusting to body movements, causing it to be painfully pulled or stretched.
The Mechanism of Nerve Gliding
The specialized movement used to treat this mechanical irritation is often called neural flossing or nerve gliding. Unlike traditional stretching, which aims to lengthen muscles or tendons, nerve gliding is designed to restore the nerve’s natural ability to slide within its protective sheath. Nerves are not meant to be stretched; they are meant to move, and these techniques encourage that motion.
The gliding movement is achieved by a carefully coordinated movement that simultaneously slackens the nerve at one end of its path while gently tensioning it at the other. This push-pull effect creates a wave of movement along the nerve’s length, encouraging it to glide through the surrounding anatomical tunnels. By mobilizing the nerve, this technique can help break down minor fibrous adhesions or scar tissue that are causing the nerve to stick.
Restoring the nerve’s mobility also has physiological benefits. Gentle, controlled movement is hypothesized to improve blood flow to the nerve itself. Nerves require a consistent supply of nutrients and oxygen, and restricted movement can impair this circulation. Improving perfusion helps reduce localized inflammation surrounding the nerve, a common source of irritation. The overall goal is to reduce mechanical tension, allowing the nerve to function with less sensitivity and pain.
Applying Safe Stretching Techniques
The application of movement for nerve pain requires a clear distinction between a traditional stretch and a neural glide. A traditional stretch attempts to tension both ends of the nerve simultaneously, which can be irritating or even harmful to an already sensitive nerve. Nerve gliding, conversely, ensures that the overall tension on the nerve remains low by coordinating joint movements that alternately load and unload the nerve.
The intensity and pace of these movements are important. Any sharp, burning, or electrical pain is a sign that the movement is too aggressive and should be immediately modified or stopped. The correct sensation should be a mild, non-painful pull or a feeling of distant tension. Movements must be performed slowly and with absolute control, focusing on the quality of the movement rather than the quantity.
For upper body nerves, such as those involved in carpal tunnel syndrome, gliding might involve tilting the neck away from the symptomatic arm while simultaneously extending the wrist. For lower body issues like sciatica, the technique might involve a seated slump posture combined with slowly pointing and flexing the ankle to move the sciatic nerve. The movement should not be held like a static stretch; instead, it is a repeated, rhythmic motion done for a short duration, such as 10 to 15 repetitions, multiple times daily.
When to Avoid Stretching
While neural gliding can be beneficial, it is not appropriate for all nerve issues, and certain symptoms are considered “red flags” that require immediate medical attention. Any sudden or rapidly worsening neurological deficit should be evaluated by a medical professional before attempting self-treatment. Progressive motor weakness, such as an inability to lift the foot (foot drop) or difficulty gripping objects, indicates significant nerve compression that needs urgent diagnosis.
Another red flag is the sudden onset of numbness or loss of sensation in the saddle area around the groin and inner thighs. This, along with any new difficulty with bladder or bowel control, suggests Cauda Equina Syndrome. In these instances, self-stretching must be avoided, as delaying treatment can risk permanent nerve damage.
If any movement, even a gentle glide, immediately and significantly increases the intensity of the pain, tingling, or numbness, the activity should be stopped. In such cases, a physical therapist or physician should be consulted immediately to assess the underlying cause.
