Burner / Stinger Injury

Upper Limb

Overview

A burner or stinger is a transient brachial plexus injury causing acute nerve irritation, typically resulting from shoulder depression with cervical lateral flexion or direct trauma to the shoulder girdle. This common sports injury presents with acute burning pain, paresthesia, and weakness in the upper limb that usually resolves within minutes to hours. While most cases are benign and self-limiting, recurrent episodes warrant thorough assessment to exclude structural pathology.

Pathophysiology

The injury mechanism involves stretch or compression of the brachial plexus nerve roots (C5-T1), most commonly at the level of the shoulder girdle during forced shoulder depression combined with cervical contralateral flexion or rotation. The plexus becomes traction-loaded or compressed against surrounding structures (scalene muscles, clavicle, first rib), causing acute neuropraxia with demyelination of nerve fibers without structural interruption. This results in transient loss of conduction velocity, manifesting as acute burning dysesthesia, paresthesia, and muscle weakness in the distribution of affected nerve roots. Predisposing factors include cervical spondylosis, narrow neuroforamina, tight cervical musculature, poor shoulder girdle stability, and previous plexus injuries.

Patient Education

A burner or stinger is a temporary nerve irritation that usually recovers quickly, but recurrent episodes or persistent symptoms require medical evaluation to rule out structural neck problems and establish preventive strategies including proper neck strengthening and technique modification.

Typical Presentation

Site

Lateral shoulder, upper arm, and forearm; often unilateral following impact; symptoms may follow dermatomal or specific nerve distribution (C5-C6 most common)

Quality

Burning, sharp, tingling, electric shock-like sensation; described as 'burner' or 'stinger' due to characteristic burning dysesthesia

Intensity

Acute onset severe pain/paresthesia (8-10/10) with rapid onset but typically brief duration; intensity decreases within minutes to hours

Aggravating

Shoulder depression with cervical lateral flexion, direct blow to shoulder area, contact sports maneuvers, rapid overhead arm movements, continued activity after initial injury

Relieving

Cessation of activity, gentle shoulder shrug/elevation, rest, removal from aggravating position, ice application, typically resolves spontaneously within minutes

Associated

Acute weakness in shoulder abductors (supraspinatus, deltoid) or arm flexors/extensors depending on nerve root involvement, transient muscle weakness lasting minutes to hours, possible mild cervical pain at time of injury, shoulder girdle muscle tightness

Orthopaedic Tests

Spurling's Test (Cervical Compression Test)

Procedure

Patient sits upright; examiner extends and laterally flexes the cervical spine toward the affected side, then applies gentle axial compression through the head.

Positive Finding

Reproduction of sharp, burning pain or electric shock sensation radiating into the shoulder, arm, or hand on the side of compression

Sensitivity / Specificity

50% / 93%

Rubinstein et al., 2007, Cochrane Database Systematic Reviews

Interpretation

Positive result suggests nerve root compression from cervical pathology; highly specific but relatively low sensitivity for cervical radiculopathy. May implicate C5–C6 nerve root involvement common in burner/stinger syndromes.

Shoulder Abduction Relief Test (SAT)

Procedure

Patient is seated or standing; examiner passively or patient actively abducts the shoulder to 90° with the hand supported on top of the head.

Positive Finding

Immediate relief or significant reduction of radiating arm or hand pain and paresthesia

Sensitivity / Specificity

See current literature / See current literature

Interpretation

Relief with shoulder abduction ('relief sign') strongly suggests cervical nerve root compression or traction injury. Positive finding supports the diagnosis of a burner/stinger due to upper trunk compression or nerve root stretch.

Upper Limb Tension Test (ULTT) – Median Nerve Bias

Procedure

Patient supine; examiner abducts the shoulder to 90°, externally rotates, extends the elbow, and dorsiflexes the wrist and extends the fingers. The contralateral cervical spine may be side-flexed away.

Positive Finding

Reproduction of burning pain, electric shock sensation, or paresthesia in the thumb, index, or middle finger distribution

Sensitivity / Specificity

See current literature / See current literature

Interpretation

Positive response suggests neural mechanosensitivity or nerve root compression affecting the upper limb. Helps differentiate nerve-mediated pain from local shoulder pathology; relevant for C5–C6 contributions to burner/stinger presentation.

Cervical Rotation Lateral Flexion (CRLF) Test

Procedure

Patient seated; examiner passively extends the neck, then rotates and laterally flexes toward the symptomatic side while gently applying overpressure.

Positive Finding

Reproduction of sharp, burning pain or radiating symptoms into the shoulder and arm on the affected side

Sensitivity / Specificity

See current literature / See current literature

Interpretation

Positive finding indicates cervical facet joint involvement or nerve root irritation; consistent with mechanism of burner/stinger injuries involving foraminal narrowing or nerve root compression.

Tinel's Sign (Cervical Nerve Root)

Procedure

Examiner percusses gently along the cervical nerve root region (lateral neck, supraclavicular area) on the affected side, typically at C5–C6 levels.

Positive Finding

Reproduction of tingling, electric shock sensation, or burning pain radiating into the shoulder, arm, or hand

Sensitivity / Specificity

See current literature / See current literature

Interpretation

Positive Tinel's sign may indicate nerve root irritation or regenerating nerve fibers; supports diagnosis of traumatic nerve involvement typical in burner/stinger injuries.

Neck Distraction Test

Procedure

Patient supine or seated; examiner applies gentle longitudinal traction (distraction) to the cervical spine, typically by cupping the occiput and gently lifting.

Positive Finding

Relief or significant reduction of radiating arm pain, paresthesia, or neurologic symptoms

Sensitivity / Specificity

See current literature / See current literature

Interpretation

Positive response (pain relief with traction) strongly suggests cervical nerve root compression or foraminal narrowing, supporting the diagnosis of burner/stinger syndrome caused by traction or compression mechanisms.

Osteopathic Techniques

Region

Cervical spine and nerve roots (C5-C6 level)

Technique

HVLA

Rationale

Cervical HVLA to address restrictive segmental dysfunction at levels C4-C5 and C5-C6 may improve neuroforaminal patency and reduce recurrent traction forces on the brachial plexus; particularly effective for cervical lateral flexion restrictions that predispose to plexus irritation

Region

Cervical and upper thoracic paraspinal muscles

Technique

Soft Tissue

Rationale

Direct soft tissue mobilization to cervical erector spinae, upper trapezius, and levator scapulae reduces muscular tension that contributes to neural compression; improved tissue quality decreases mechanical irritability of nerve roots

Region

Anterior and middle scalene muscles

Technique

MET

Rationale

Muscle energy technique specifically targeting scalene muscles decompresses the brachial plexus as it passes between these muscles; reduces primary compression point and decreases recurrence risk by improving interscalene space

Region

Shoulder girdle and upper limb

Technique

Articulation

Rationale

Gentle articulation of glenohumeral joint and scapulothoracic mechanics improves shoulder girdle stability and proprioception, reducing predisposition to traction injuries by optimizing biomechanics

Region

Brachial plexus and peripheral nerves

Technique

Soft Tissue

Rationale

Neural mobilization and gentle soft tissue work along the plexus pathway (axilla, lateral arm) reduces adhesions and improves neural gliding; restores normal mechanosensitivity of irritated nerve segments

Region

Upper thoracic spine (T1-T4)

Technique

Articulation

Rationale

Upper thoracic restriction contributes to altered shoulder girdle mechanics and increased cervical compensation; improving thoracic mobility reduces secondary cervical strain and plexus irritability

Add-On Approaches

Chinese Medicine

Acupuncture to C5-C6 dermatomal distribution and local points around shoulder girdle; moxibustion to upper back may improve Qi circulation and reduce inflammation of affected meridians (large intestine and triple burner)

Chiropractic
