Overview of Upper Left Back & Shoulder Blade Pain: Causes & Fixes

Struggling with a dull ache or sharp pain under your left shoulder blade? Discover the musculoskeletal causes, postural triggers, and physiotherapy fixes.

The upper left back consists of the thoracic spine, ribs, scapula (shoulder blade), and multiple muscle layers (rhomboids, trapezius, erector spinae) that stabilize the shoulder girdle and support breathing mechanics.

Common Causes & Pathophysiology

Postural imbalances (like hunching over computers), rhomboid muscle strains from heavy lifting, rib facet joint sprains, and referred pain from the neck (cervical radiculopathy) are the most common musculoskeletal causes.

Common symptoms include localized tenderness, sharp pain during movements, swelling, bruising, and muscular tightness or spasms in the affected region.

Evidence-Based Physiotherapy Treatment

Our physiotherapy approach focuses on: 1) Trigger point release (manual therapy or dry needling) for rhomboid knots, 2) Thoracic spine mobilization to restore rib/vertebral glide, 3) Scapular stabilization exercises (Y-T-W drills), and 4) Cervical alignment correction.

Rehabilitation must be progressive, moving from pain reduction to strength restoration. Patients are advised to work under guided supervision to prevent reinjury.

Clinical Outlook & Next Steps

Early and accurate diagnosis is critical to avoid transforming acute tissue strains or nerve compressions into chronic dysfunction. If you suspect an injury, consult a physiotherapist for a personalized evaluation.
