Nerve Entrapment and Pinched Nerves: Symptoms, Causes and Treatment
Pain, tingling, numbness or weakness in the arms and legs can sometimes be associated with irritation or compression of a nerve. These symptoms may originate from the spine or develop where a peripheral nerve passes through muscles, connective tissue or other anatomical structures.
At Cammeray Chiropractic & Performance Centre, we assess nerve-related symptoms to help identify their possible source, understand contributing mechanical factors and develop an appropriate management plan.
What Is Nerve Entrapment?
Nerve entrapment occurs when a peripheral nerve becomes compressed or irritated as it travels through a confined anatomical space.
Common examples include:
Carpal tunnel syndrome: Compression of the median nerve at the wrist, often producing tingling or numbness in the thumb, index and middle fingers.
Cubital tunnel syndrome: Irritation or compression of the ulnar nerve around the elbow, potentially affecting the ring and little fingers.
Cervical radiculopathy: Irritation or compression of a cervical nerve root, which may cause pain, tingling, numbness or weakness extending from the neck into the shoulder, arm or hand.
Lumbar radiculopathy: Irritation of a lumbar or sacral nerve root, sometimes producing radiating pain, altered sensation or weakness in the leg.
Common fibular nerve entrapment: Compression around the outside of the knee, potentially affecting sensation or muscle function in the lower leg and foot.
Although these conditions can produce similar symptoms, their underlying causes and appropriate treatments may differ.
Understanding Neural Tension
Nerves need to move and adapt as the body changes position. During normal movement, peripheral nerves glide relative to surrounding muscles, fascia and joints.
Neural mechanosensitivity describes an increased sensitivity of neural tissues to mechanical loading or movement.
For example, certain arm or neck movements may reproduce tingling, pulling or radiating discomfort when a nerve or its surrounding tissues are irritated.
Importantly, increased neural sensitivity does not necessarily indicate that a nerve is physically trapped or structurally damaged.
Common Symptoms of Nerve Irritation
Symptoms vary depending on the nerve involved and the location and severity of the problem.
1. Radiating Pain
Pain may travel from the neck into the shoulder and arm, or from the lower back into the buttock and leg. It can feel sharp, shooting, burning or electric.
2. Numbness and Tingling
Altered sensation may occur in particular fingers, areas of the hand, forearm, leg or foot. The distribution of symptoms can provide useful clues about which nerve structures may be involved.
3. Muscle Weakness
Some nerve conditions affect the ability to activate specific muscles. Patients may notice reduced grip strength, difficulty lifting the foot or weakness during particular movements.
4. Increased Sensitivity to Movement
Certain positions or movements may aggravate symptoms by increasing mechanical loading on sensitive neural structures.
5. Changes in Sensation
Some people experience reduced sensitivity to touch, while others notice burning, hypersensitivity or uncomfortable sensations in the affected region.
What Causes Nerve Entrapment or Irritation?
Potential contributing factors include:
Cervical or lumbar disc protrusions
Degenerative narrowing of spinal nerve openings, known as foraminal stenosis
Local compression within anatomical tunnels
Swelling or inflammation around a peripheral nerve
Trauma or repetitive mechanical loading
Prolonged positions that place pressure on vulnerable nerves
Certain systemic medical conditions, including diabetes
Not all tingling or radiating pain originates from a compressed nerve. A careful clinical assessment is important because muscular, joint-related, vascular and other neurological conditions can sometimes produce similar symptoms.
How Do We Assess Nerve-Related Symptoms?
At Cammeray Chiropractic & Performance Centre, assessment begins with a detailed clinical history and examination.
Depending on the presentation, this may include:
Neurological Examination
Testing muscle strength, reflexes and sensation can help identify patterns of neurological dysfunction and determine whether further investigation is required.
Neurodynamic Testing
Upper and lower limb neurodynamic tests assess how symptoms respond to movements that mechanically load neural structures.
These tests are interpreted alongside the clinical history and neurological examination rather than being used as standalone diagnostic tests.
Cervical Thoracic and Lumbar Spine Assessment
Spinal movement, joint function and relevant orthopaedic testing may help determine whether symptoms are associated with irritation of a spinal nerve root.
Functional Movement Assessment
We may assess posture, movement patterns, muscular strength and the activities that aggravate or relieve symptoms.
Imaging and Specialist Investigation
MRI, diagnostic ultrasound, nerve conduction studies or electromyography may be appropriate in selected cases, particularly where there is significant weakness, persistent neurological dysfunction or diagnostic uncertainty.
Not every patient requires imaging or electrodiagnostic testing.
Treatment and Rehabilitation Options
Management depends on the underlying diagnosis, symptom severity and whether there is evidence of neurological impairment.
A conservative management program may include:
Manual therapy
Appropriate spinal or peripheral joint mobilisation/manipulation may help address associated musculoskeletal pain and movement restrictions. Manual therapy is selected according to the clinical presentation and is not assumed to physically release a compressed nerve.
Neural mobilisation exercises
Carefully prescribed nerve-gliding movements may help improve tolerance to movement in selected patients. Exercises should be adjusted to avoid significant or sustained aggravation of neurological symptoms.
Strengthening and rehabilitation
Progressive exercise can address associated weakness, reduced movement capacity and limitations in everyday or sporting activities.
Activity and ergonomic modification
Changes to aggravating activities, work positions or training loads may help reduce mechanical irritation while recovery progresses.
Medical referral when appropriate
Some nerve conditions require medical investigation, medication, injections or surgical assessment, particularly when significant or progressive neurological deficits are present.
When Should You Seek Medical Attention?
New or worsening muscle weakness, progressive loss of sensation or persistent neurological symptoms warrant prompt medical assessment.
Sudden severe weakness, new bladder or bowel dysfunction, numbness around the groin or saddle region, or rapidly progressive neurological symptoms require urgent medical evaluation.
Nerve Entrapment Assessment in Cammeray
If you're experiencing persistent tingling, numbness, radiating pain or suspected nerve irritation, identifying the underlying cause is an important first step.
At Cammeray Chiropractic & Performance Centre, we combine musculoskeletal and neurological assessment with individualised rehabilitation strategies to help patients understand their symptoms and explore appropriate treatment options.
