Shoulder pain?
At what angle does it hurt?

60° to 120°, the middle of the arc: impingement or the cuff tendons.Only at the very top: the AC joint.Sample only: pain from 70° to 115°. Mark your own in the test.

Rotator cuff tear, impingement, or frozen shoulder — they look identical to you and nothing alike to a surgeon. Where pain appears as you raise your arm is a real clinical test. Confirm your plan with your own clinician.

Before the appointment

Two things to do in about five minutes each. Both run on this device; nothing is sent. Emergency signs are listed first on both pages.

Try it right now

At what angle does it hurt?

Where pain appears as you raise your arm is a real clinical test — the painful arc. Sweep the arm, mark where it hurts, and see which structure that points to.

0°

Drag the hand up and down to mirror raising your arm.

Raise your arm out to the side. As you sweep the handle, mark where pain starts and where it eases or stops.

Or, if the limit is not pain:

Shoulder Mobility Self-Test

Five simple movements you can do right now. Each takes about 30 seconds. No equipment needed.

Stop if any movement causes sharp or severe pain. This is a screening tool, not a diagnosis.

1

Raise arm straight overhead

Stand with feet shoulder-width apart. Raise your affected arm straight up, reaching as high as possible toward the ceiling.

2

Reach behind your back

Reach your affected arm behind your back and try to touch between your shoulder blades (as if reaching for a zipper).

3

Reach across your body

Reach your affected arm across your chest to touch the opposite shoulder. Note any pain as you do this.

4

External rotation

Hold your elbow at your side at 90 degrees (like you're carrying a tray). Rotate your forearm outward away from your body, as if opening a door.

5

Sleep on affected side

Think about the last few nights. Are you able to sleep comfortably on your affected shoulder?

The four most common shoulder problems

Shoulder pain looks similar on the surface. The underlying diagnosis changes whether you need PT, injections, or surgery.

Evidence-based timelines

What recovery actually looks like

Shoulder recovery is highly condition-specific. Select your diagnosis to see realistic milestones — so you know what to expect before you start treatment.

Shoulder Impingement

Conservative treatment — no surgery

Many people improve without surgery. Surgery (subacromial decompression) is reserved for 3–6 months of failed PT.

1

Week 1–2

Activity modification + NSAIDs

Rest from aggravating overhead activities. Ice 15 min, 3× daily. Over-the-counter NSAIDs reduce acute inflammation. Avoid behind-the-neck exercises.

2

Week 2–6

Physical therapy begins

Scapular stabilization, posterior capsule stretching, and posture correction. Rotator cuff external rotation strengthening with light resistance.

3

Week 6–12

Progressive strengthening

Many people have much less pain by this point. Overhead activity gradually reintroduced. Corticosteroid injection considered if pain persists at this point.

4

3–6 months

Full function for most

Return to all activities. Many people recover without surgery. If pain persists beyond 3–6 months of structured PT, surgical evaluation is appropriate. (NICE 2023)

NICE Shoulder Pain Guideline 2023; AAOS Impingement Management

Ask Sage about your recovery

Recovery timelines are general estimates. Individual outcomes vary based on age, tear size, pre-operative function, and adherence to physical therapy. Consult your surgeon for a personalized plan.

When to escalate care

Step-by-step: when conservative care is not enough

Most shoulder conditions are treated conservatively first. But each has a specific point where continuing to wait causes harm. Here is the evidence-based escalation ladder for each condition.

1

Step 1 · Weeks 1–6

Activity modification + NSAIDs + targeted PT

Pain improving, overhead activity tolerable

2

Step 2 · If not improving at 6 weeks

Corticosteroid injection + continued PT

2–6 weeks of significant pain reduction; allows PT progress

Escalate if: No improvement after injection + 6 weeks PT → Step 3
3

Step 3 · 3–6 months of failed conservative care

Surgical evaluation: subacromial decompression

Short outpatient procedure; recovery is often measured in weeks; ask your surgeon what to expect

Surgical referral criteria — Shoulder impingement

Escalate to surgical evaluation when: pain persists after 3–6 months of structured PT, at least one corticosteroid injection has been tried, and pain significantly limits daily function. Imaging (MRI or ultrasound) before referral confirms pathology. (NICE NG59 2023)

NICE Shoulder Pain Guideline NG59 2023; AAOS Impingement Management

Find a surgeon for a second opinion

Escalation timelines are general estimates. Individual circumstances — tear size, age, activity level, medical history — significantly affect timing. A surgeon with your imaging and history provides the definitive recommendation.

What you should know

Key information about shoulder conditions and treatment options.

1

Rotator Cuff Tears

Full-thickness rotator cuff tears affect 25% of people in their 60s and 50% of people in their 80s. Many atraumatic full-thickness tears are managed without surgery. Surgical repair provides better functional outcomes for acute traumatic tears and large tears causing significant weakness. The tendon takes 10–12 weeks to heal biologically — recovery cannot be rushed. (PMC11692865)

2

Frozen Shoulder

Adhesive capsulitis progresses through three stages: freezing (6 weeks to 9 months), frozen (4–6 months), and thawing (6 months to 2 years). Total duration without treatment: up to 3 years. Corticosteroid injection during the freezing phase is the single most evidence-backed intervention. Diabetes significantly worsens prognosis and prolongs recovery. (AAOS OrthoInfo; StatPearls NBK532955)

3

Shoulder Impingement

The most common cause of shoulder pain in adults. Tendons become pinched under the acromion during arm elevation, creating a painful arc between 60° and 120°. Strength is usually preserved — distinguishing it from rotator cuff tears. Many people improve without surgery with structured PT focused on scapular stabilization and rotator cuff strengthening. (NICE 2023; AAOS CPG)

4

When Surgery Helps

Surgery is appropriate for: full-thickness rotator cuff tears with significant weakness in active patients; recurrent shoulder dislocations (Bankart repair); end-stage arthritis (shoulder replacement); and impingement failing 3–6 months of PT. A good surgeon exhausts conservative options first. Diagnosis determines the operation — no single shoulder surgery fits all conditions.

5

Physical Therapy: What Actually Works

Evidence is strongest for scapular stabilization (lower trapezius, serratus anterior), posterior capsule stretching, and progressive rotator cuff strengthening. Avoid behind-the-neck exercises, sustained overhead positions, and sleeping on the affected side. For impingement, external rotation strengthening with light resistance produces the most consistent results. A therapist should assess whether active or passive motion is more restricted — this guides the protocol.

Shoulder Arthritis & Replacement

Shoulder osteoarthritis is less common than knee or hip OA. Symptoms: progressive pain, grinding, and stiffness at the glenohumeral joint. Conservative management (PT, NSAIDs, corticosteroid injections) should be maximized before surgery. Total shoulder replacement can reduce pain substantially, and implants are designed to last many years. Reverse total shoulder arthroplasty is used when the rotator cuff is irreparably damaged — it actually requires less intact tissue than standard replacement.

When to seek help

See a healthcare provider if you experience any of these warning signs. Some need care today, or 911 now, as marked.

1

Sudden inability to lift or rotate the arm after an injury

Get seen today, at your doctor, urgent care or an ER. If after a fall or a blow you cannot move the arm at all, or the shoulder looks out of place: call 911 now. Call 911

2

Shoulder pain that persists at rest or wakes you at night

3

Visible deformity or swelling of the shoulder

After a fall or a blow, if the shoulder looks out of place or deformed, or you cannot move the arm: call 911 now (possible dislocation or break). Call 911

4

Shoulder pain with shortness of breath or chest tightness

Call 911 now: with shoulder or arm pain, chest pressure or discomfort, shortness of breath, a cold sweat, nausea or lightheadedness is a possible heart attack. Call 911

5

Numbness or tingling running down the arm into the hand

6

Shoulder that feels like it slips out of place

7

Increasing weakness when lifting everyday objects

8

Fever or warmth around the shoulder joint

Hot, swollen and very painful, especially with a fever: get seen today, at your doctor, urgent care or an ER (a joint infection needs fast care).

When to Worry

Shoulder pain red flags: when to seek care urgently

Shoulder pain is extremely common and usually not serious. But several presentations require urgent or emergency evaluation.

Go to the emergency room for: shoulder pain after significant trauma with visible deformity (fracture or dislocation); a shoulder that is visibly "out of socket" and cannot be moved (acute dislocation requiring closed reduction); sudden severe shoulder weakness after a fall in a person over 55 (acute massive rotator cuff tear with pseudoparalysis); and shoulder pain accompanied by chest pain, shortness of breath, sweating, or pain radiating to the jaw — these can be signs of a cardiac event, as heart attack pain frequently refers to the left shoulder and arm.

See your doctor within 1 week for: shoulder pain that started suddenly with a specific injury mechanism; new significant weakness when lifting the arm to the side or forward; shoulder swelling with fever (possible septic joint); or pain that was improving but has suddenly worsened.

Schedule a routine appointment for: pain that has persisted more than 4–6 weeks without improvement; night pain disrupting sleep; pain limiting overhead activities; or progressive stiffness suggesting early frozen shoulder.
