Physiotherapy vs Cortisone Injections - Which Gives Better Long-Term Results?
Quick answer: Cortisone gives fast relief (days) but wears off in 6-12 weeks, masks the problem, and can weaken tendons with repeat use. Physiotherapy is slower to start but produces better outcomes at 6 and 12 months - it treats the cause. Current guidelines: try physio first for most tendinopathies and musculoskeletal pain. Reserve injection for severe pain blocking rehab, or specific inflammatory conditions. Best approach often: single injection + structured physio in the pain-reduced window.
Side-by-Side Comparison
| Feature | Physiotherapy | Cortisone Injection |
|---|---|---|
| Onset of relief | 1-3 weeks | 2-7 days |
| Duration | Long-term with exercises | 6-12 weeks typical |
| Treats cause | Yes | No - anti-inflammatory only |
| Recurrence rate | Low if adherent | High (50-80%) |
| Tissue risk | None | Tendon weakening with repeat |
| Cost per treatment | RM80-150 | RM200-500 |
| Sessions needed | 4-8 | 1-3 injections |
| Side effects | Rare | Flare, skin changes, glucose spike |
The Landmark Evidence
Coombes et al, Lancet 2010 (tennis elbow):
- 4 weeks: cortisone group best
- 6 months: physio group overtook
- 12 months: cortisone group worst outcomes, worse than no treatment
Pattern replicated in shoulder, knee, and plantar fasciitis studies. Short-term relief can mask underlying problem and enable premature return to activity.
How Cortisone Works
- Powerful anti-inflammatory
- Reduces local swelling and pain
- Does NOT heal tissue
- Does NOT strengthen tissue
- Can be therapeutic OR diagnostic
- Effect peaks 2-6 weeks
- Wears off as body metabolises steroid
How Physio Works
- Assesses cause
- Manual therapy and modalities for symptoms
- Loading programme rebuilds tendon / joint tolerance
- Education on pacing and activity
- Prevention strategy
- Addresses the actual problem, not just pain
When Cortisone Is Indicated
Good Fits
- Frozen shoulder (adhesive capsulitis) - combined with physio works well
- Severe bursitis - hip, subacromial
- Rheumatoid / inflammatory arthritis flare
- Trigger finger / de Quervain's
- Carpal tunnel syndrome
- Morton's neuroma
- Facet joint arthritis (image-guided)
- Pain so severe it blocks rehab
Diagnostic Use
- If injection eliminates pain → confirms pain source
- Guides treatment planning
When Cortisone Should Be Avoided or Delayed
- Chronic tendinopathy (long-term worse outcomes)
- Weight-bearing tendons with repeat injections (Achilles, patellar, rotator cuff)
- Recent injection < 3 months prior
- Active infection in area
- Diabetic patients with unstable glucose
- Anticoagulants (individual assessment)
Limits on Injection Frequency
- Most specialists: maximum 3 in same area per year
- Weight-bearing tendons: usually 1 lifetime, due to rupture risk
- Joint injections: space 3-6 months apart
- Cumulative dose considerations
- If third injection doesn't last, stop - treatment failing
The Combined Approach (Often Best)
Single injection + immediate physio:
- Injection reduces pain to enable rehab
- Wait 48-72 hours for local soreness
- Start physio - address root cause
- Use 6-12 week window for loading programme
- Complete rehab before injection wears off
- Usually no need for second injection
Without physio during the window, pain almost always returns.
Common Conditions - Which First?
Shoulder Impingement / Rotator Cuff Tendinopathy
- Physio first (6-12 weeks loading programme)
- Injection if pain blocks exercise
- Combined approach evidence-based
Frozen Shoulder (Adhesive Capsulitis)
- Injection + physio - synergistic in frozen phase
- Injection alone limited long-term
- Physio essential for mobility recovery
Tennis / Golfer's Elbow
- Physio first - eccentric loading is gold standard
- Cortisone for early severe pain only
- Repeated injections worsen long-term outcome
Plantar Fasciitis
- Physio first - calf stretching, loading, footwear
- Injection if failed 6-8 weeks
- Avoid repeat injections (fat pad atrophy)
Trigger Finger
- Injection effective first-line
- Physio for post-injection mobility
- Surgery if injection fails
Knee Osteoarthritis
- Exercise is first-line
- Injection as adjunct for flares
- Not every 3 months routine
Carpal Tunnel
- Splinting + ergonomic first
- Injection for symptom control
- Surgery for persistent
Hip Bursitis (Greater Trochanter)
- Physio glute strengthening first
- Injection for severe pain
- Combined best
Side Effects of Cortisone
- Post-injection flare (24-48 hours of increased pain) - 10-20%
- Skin pigmentation changes at injection site
- Fat pad atrophy / dimpling
- Transient glucose elevation (diabetic concern)
- Facial flushing
- Menstrual irregularity (temporary)
- Tendon weakening with repeats
- Rare: infection, bleeding

- Injections usually covered by insurance
- Ask about cumulative limits
What to Ask Your Doctor
- Have we tried 4-6 weeks of physio?
- Is this tendon at risk of weakening?
- Is this my first injection in this area?
- Will you pair it with physio?
- What if it doesn't work?
Common Mistakes
- Repeated injections without rehab (chasing relief)
- Using injection as a sports comeback shortcut
- Not doing physio in the 6-12 week window
- Skipping assessment before injection
- Expecting one injection to solve chronic tendinopathy
- Declining injection when pain blocks rehab (sometimes injection enables progress)
Red Flags - See a Doctor
- Severe uncontrolled pain
- Fever, redness, swelling (possible infection)
- Sudden weakness after injection
- Signs of tendon rupture after injection
- Unexplained weight loss or cancer history
Frequently Asked Questions
How many cortisone injections are safe? Most specialists limit to 3 per site per year. Weight-bearing tendons often just one in a lifetime.
Can I do physio right after an injection? Wait 48-72 hours for soreness to settle, then begin. This is the recommended approach.
Why does my doctor offer injection first? Quicker to administer; immediate satisfaction. Evidence now supports physio-first for most conditions. You can request physio.
Will cortisone damage my tendon? Single injection - low risk. Repeated injections in weight-bearing tendons - real risk of weakening or rupture.
How fast does cortisone work? 2-7 days typical. Some patients feel better immediately; others need a week.
Will pain come back after cortisone? Almost always if underlying cause not addressed. That's why physio matters.
Is there an alternative to cortisone? Depending on condition: PRP injections, shockwave, physio alone, hyaluronic acid for osteoarthritis.
Can I do physio without seeing a doctor? Yes - Malaysian physios are first-contact.
Fix the Cause, Not Just the Pain
Cortisone is a useful tool - especially combined with rehab - but not a stand-alone solution. Physio addresses why the pain is there. For most conditions, try physio first or alongside.
