What shoulder pain can mean

Overview Pain can come from the rotator cuff tendons, bursa, joint arthritis, a frozen shoulder (stiff capsule), or from the neck (pinched nerve). Less common but important: fracture/dislocation after a fall and referred pain from the heart, lungs, or abdomen.

Clues: pain with reaching overhead or behind, night pain, weakness when lifting the arm, stiffness (loss of range), or tingling down the arm (often neck-related).

When to call emergency

  • Shoulder/arm pain with chest pressure, shortness of breath, sweating, or nausea (possible heart attack)
  • After a fall: obvious deformity, severe pain, or inability to move/hold the arm (possible fracture/dislocation)
  • Fever, red hot swollen shoulder, or feeling very unwell (possible joint infection)
  • New weakness or numbness in the hand/arm after neck injury

These need urgent care.

Common causes & clues

CauseTypical featuresNotes
Rotator cuff tendinopathy/tear Pain with lifting/overhead reach; night pain; weakness (tear) Common with age; often supraspinatus tendon
Subacromial impingement / Bursitis Painful arc (60–120°); worse reaching to the side or behind Often responds to posture and cuff strengthening
Adhesive capsulitis (frozen shoulder) Stiffness + pain; limited external rotation and reaching Stages: freezing → frozen → thawing; common with diabetes, thyroid disease
Glenohumeral osteoarthritis Deep joint pain, creaking, stiffness, loss of rotation Gradual onset; X-ray shows joint space loss
Acromioclavicular (AC) joint arthritis Tender top of shoulder; pain with cross-body reach Localized to AC joint; lifting/carrying aggravates
Cervical radiculopathy Neck pain; shooting pain/tingling down arm; worse with neck movement May have hand numbness/weakness; Spurling’s positive
Polymyalgia rheumatica Morning stiffness/pain in shoulders/hips; age >50 Often elevated inflammatory markers; treatable
Calcific tendinitis Sudden severe pain; limited motion Calcium deposit in tendon; visible on X-ray

First steps at home

Calm the pain

  • Relative rest: avoid painful overhead/lifting for a few days; keep the arm gently moving below shoulder height.
  • Ice 10–15 minutes 2–3×/day for flares; warm shower before exercises if stiff.
  • Medicine safety: many seniors use acetaminophen first. Ask before NSAIDs if you have kidney, ulcer, heart, or BP issues.

Posture & setup

  • Support the elbow on a pillow when sitting; avoid prolonged slumped posture.
  • Keep frequently used items between waist and chest height.
Call your clinician if pain lasts >2–3 weeks, limits sleep, or if you notice weakness, catching/locking, or significant stiffness.

Gentle exercises

Phase 1 — Motion (daily)

  • Pendulums: Bend forward, relax the arm, gently swing small circles 20–30 seconds.
  • Table slides: Slide forearms forward on a table, stop before pain, hold 3–5 seconds × 10.
  • External rotation with stick: Elbows at side, use a stick/towel to gently turn hands outward × 10.

Phase 2 — Strength (3–4×/week)

  • Isometrics against a wall (gentle press out/in/forward/back) × 5–10 seconds each.
  • Light band rows and external rotation once pain is controlled.
Mild stretch discomfort is OK; sharp pain is a stop sign. Progress gradually.

What clinicians may do

StepPurposeExamples
History & exam Localize pain; check motion & strength Painful arc, empty can, Hawkins/Kennedy, cross-body, neck tests
X-ray Rule out fracture/arthritis; calcific deposits AP, outlet, AC views
Ultrasound / MRI Confirm rotator cuff tear/bursitis Useful if persistent weakness or surgery considered
Labs (selected) Inflammatory or systemic cause ESR/CRP for PMR; infection workup if fever/redness
Injections Reduce inflammation/pain to enable therapy Subacromial steroid; hydrodilatation in frozen shoulder

Treatment options

Activity + PT

  • Guided home program and physical therapy improve pain and function for most rotator cuff and impingement cases.
  • For frozen shoulder: gradual stretching and pain control through phases.

Medicines

  • Acetaminophen as first choice for many; topical NSAIDs may help localized pain.
  • Oral NSAIDs only if appropriate—discuss kidney, stomach, heart, and BP risks.

Procedures

  • Corticosteroid injections for bursitis/impingement (limit frequency).
  • Surgery considered for large/full-thickness tears with loss of function or failure of rehab.
Plans are individualized—consider other conditions (diabetes, heart, kidney) and medicine interactions.

What to track

  • Pain (0–10) morning/evening; sleep disturbance.
  • Functional goals: reaching overhead, fastening bra/belt, behind-back reach.
  • Triggers (lifting, overhead work) and response to exercises/medicine.
A 2–3 week log helps fine-tune exercise progressions and timing of therapy or imaging.

Quick answers

Do I need an MRI right away?

Not usually. Many shoulder problems improve with exercises and time. Imaging is considered if weakness persists, injury was severe, or rehab fails.

What’s the difference between frozen shoulder and rotator cuff?

Frozen shoulder = stiff shoulder with limited motion in all directions. Rotator cuff issues = pain and weakness, usually with near-normal passive motion.

Should I use a sling?

Short-term comfort is okay after injury, but prolonged sling use can worsen stiffness. Keep gentle motion going unless told otherwise.

When to see ortho?

Significant weakness, recurrent dislocations, suspected large tears, or pain/function not improving after several weeks of good rehab.
