Understanding the Dorsal Scapular Nerve Entrapment: A Hidden Cause of Shoulder Blade Pain

Date: August 16, 2025

Shoulder blade pain is one of the most common complaints we see at Pain Free Health. While many patients assume it’s due to muscle knots or posture, one overlooked cause is irritation of the dorsal scapular nerve—a small but important nerve that originates from the C5–C6 cervical roots.

Anatomy of the Dorsal Scapular Nerve

Origin: Primarily from the C5 nerve root, sometimes with input from C4 or C6.

Pathway: Travels through the middle scalene muscle, deep under the levator scapulae, and along the medial border of the scapula beneath the rhomboids.

Innervation: Provides motor supply to the rhomboid major, rhomboid minor, and levator scapulae, which are key stabilizers of the shoulder blade.

Why It Matters: Pain and Dysfunction

When irritated, the dorsal scapular nerve can cause:

  • Deep aching pain between the shoulder blades
  • Neck stiffness and limited rotation
  • Weakness in scapular retraction and elevation
  • Pain aggravated by poor posture, prolonged sitting, or overhead lifting

Unlike true radiculopathy, patients often don’t experience numbness or tingling—making diagnosis tricky.

Link to C5–C6 Irritation

Because the dorsal scapular nerve arises from the C5–C6 nerve roots, conditions such as cervical disc bulges, foraminal narrowing, or facet joint arthritis can directly affect it. This results in a combination of neck pain and scapular pain, often mistaken for muscular tension or even rotator cuff problems.

Differential Diagnosis

It’s important to distinguish dorsal scapular nerve pain from:

  • Myofascial trigger points (rhomboids, levator scapulae)
  • Thoracic facet joint pain
  • True C5–C6 radiculopathy (with sensory/motor changes)
  • Shoulder rotator cuff injuries
  • Cardiac referral pain (in some cases)

Clinical Assessment at Pain Free Health

Our physiotherapists perform a detailed evaluation, including:

  • Palpation along the medial scapular border
  • Resisted scapular retraction strength testing
  • Scalene muscle compression tests
  • Neurological exam for C5–C6 function
  • Imaging referral (MRI) when cervical root irritation is suspected

Treatment & Rehabilitation

At Pain Free Health, our approach focuses on both nerve decompression and muscle rebalancing:

  • Posture correction & ergonomic training
  • Manual therapy for cervical mobility and scalene release
  • Targeted stretching (levator scapulae, scalenes)
  • Strengthening (rhomboids, trapezius, deep neck flexors)
  • Cervical traction when root compression is contributing
  • Activity modification to reduce repetitive strain

Prognosis

Early recognition leads to faster recovery, while chronic irritation can cause muscle weakness or atrophy. Addressing both the local entrapment and the cervical root involvement is key to long-term relief.

At Pain Free Health, we specialize in managing complex neck and shoulder conditions like dorsal scapular nerve irritation. If you’re struggling with persistent pain between the shoulder blades or neck tightness, our physiotherapy team can provide targeted assessment and treatment.
