Shoulder Pain: The Most Common Causes (and What to Do)

A clear overview of the most common shoulder problems we see — and how each one is typically treated.

The usual suspects

  • Rotator cuff tendinopathy — gradual onset, painful arc with reaching, weakness with elevation. Loading-based rehab is the foundation.
  • Subacromial pain — pain with overhead and across-body motions. Often responds to scapular and shoulder-girdle strengthening.
  • Frozen shoulder (adhesive capsulitis) — significant stiffness with pain, often without a clear injury. Phases over 12–24 months; treatment shortens phases.
  • Rotator cuff tears — partial or full thickness. Many do well with rehab; surgical decision-making depends on tear size, function, age, and goals.
  • AC joint sprains — direct trauma, point tenderness over the joint. Most resolve with structured rehab.
  • Instability and labral issues — often in younger, active populations. Strength and motor-control programs are central.

What rehab typically includes

Range-of-motion work, manual therapy, modalities for early symptom relief, progressive strengthening (the cornerstone of shoulder rehab), and education on dose and posture. Surgical cases follow protocol-aligned plans.

When to seek care

Persistent pain past 2–3 weeks, weakness, sleep disruption from shoulder pain, or recent trauma with significant bruising or deformity.
