InstantMed Clinical Team
AHPRA-registered medical team · Reviewed 2026-03
Muscle strains are among the most common workplace injuries, and they are well-suited to telehealth assessment because the diagnosis is almost entirely history-based. I ask about the mechanism (what were you doing when it happened?), the location, the severity (can you still move the affected area?), and whether there was an audible pop or snap. Most strains are mild to moderate and recover fully with conservative management - rest, ice, gentle movement, and over-the-counter pain relief. The key distinction I make is between a simple strain and a potential tear or fracture. Red flags include inability to bear weight, significant swelling, visible deformity, or numbness below the injury. For workplace injuries, I document the mechanism clearly for WorkCover purposes if needed, though WorkCover claims require an in-person assessment. A medical certificate for a muscle strain is entirely appropriate, particularly for physical work.
Treatment
TreatingMuscleStrain
Muscle strains are managed conservatively with analgesics, relative rest, and graduated return to activity. The eTG recommends paracetamol as first-line, with short-course NSAIDs added for moderate-to-severe pain. Topical NSAIDs (diclofenac gel) reduce systemic exposure and are useful for superficial strains. Ice in the first 48-72 hours, then heat; complete immobilisation delays recovery.
Paracetamol
Panadol, Panamax
Class:Analgesic
Typical dose:500-1000mg every 4-6 hours; maximum 4g per 24 hours
PBS:Available OTC without prescription
- First-line oral analgesia for muscle strains
- Can be combined with ibuprofen for superior pain control
- Safe for most adults; avoid in significant liver disease
Ibuprofen
Nurofen, Advil
Class:NSAID (non-steroidal anti-inflammatory drug)
Typical dose:200-400mg every 6-8 hours with food for 5-7 days
PBS:Available OTC without prescription
- Reduces inflammation and pain; evidence supports short-course NSAIDs for acute soft-tissue injury
- Take with food; avoid if history of gastric ulcer, renal impairment, or cardiovascular disease
- Limit to 5-7 days for acute strains to avoid gastrointestinal side effects
Diclofenac diethylamine (topical)
Voltaren Emulgel, Voltaren Osteo Gel
Class:Topical NSAID
Typical dose:Apply 2-4g to affected area 3-4 times daily; rub in gently
PBS:Available OTC (Schedule 3, pharmacist supply) without prescription
- Effective for superficial muscle and soft-tissue injuries with minimal systemic absorption
- Well tolerated; local skin reactions are the most common side effect
- Cochrane review supports topical NSAIDs as effective as oral NSAIDs for localised pain with fewer GI side effects

Specialist referral: Refer to a sports medicine physician or physiotherapist if the strain does not improve within 4-6 weeks, if a complete muscle tear is suspected (audible pop, visible gap, severe weakness), or if the injury is work-related and a WorkCover assessment is required.
Muscle Strain in Australia
Musculoskeletal conditions are the leading cause of workplace injury claims in Australia (Safe Work Australia)
Back strains account for 22% of all serious workplace injury claims in Australia
The direct cost of work-related musculoskeletal injuries in Australia exceeds $24 billion per year
Manual handling injuries (lifting, carrying, bending) are the most common mechanism of workplace muscle strains
Recovery
Whattoexpect
Typical recovery timeline and return-to-work guidance for most patients.
Typical recovery
Grade 1 (mild): 1-2 weeks. Grade 2 (moderate, partial tear): 3-6 weeks. Grade 3 (complete tear): 6-12 weeks, may need surgical repair. Most strains peak in pain within the first 48-72 hours and improve steadily from there.
Return to work
For desk work: 1-3 days for mild strains. For physical or manual labour: 1-3 weeks depending on severity and the specific muscles involved. A graduated return to full duties is safer than returning too quickly - re-injury during recovery is common and takes longer to heal.
When to reassess
See a doctor if you heard a pop or snap at the time of injury, if you cannot move the affected area at all, if there is significant swelling or bruising, if pain is worsening after 48 hours despite rest and ice, or if numbness or tingling develops below the injury.
Self-Care
ManagingMuscleStrainathome
Evidence-based tips to support your recovery alongside medical treatment.
Follow the RICE protocol for the first 48-72 hours: Rest, Ice (20 minutes on, 20 off), Compression, Elevation
Avoid heat in the first 48 hours - ice reduces inflammation, while heat increases blood flow and swelling early on
After 48-72 hours, switch to gentle movement and heat - prolonged rest actually delays healing
Paracetamol and ibuprofen together provide better pain relief than either alone
Gentle stretching within pain-free range promotes healing and prevents stiffness
Gradually increase activity - if a movement hurts, reduce the range but do not stop moving entirely
FAQ
CommonquestionsaboutMuscleStrain
Answers to the most common questions from patients.
Yes. Muscle strains can prevent you from working, especially in physical roles. Our doctors can provide certificates for recovery time.
Mild strains heal in 1-2 weeks. Moderate strains take 3-6 weeks. Severe tears may need 3+ months. Recovery depends on the muscle and severity.
Ice for the first 48-72 hours to reduce swelling, then heat to improve blood flow and healing. Both can help with pain management.
This depends on your role. Desk workers may return sooner. Physical workers may need 1-2 weeks. Our doctors can advise based on your situation.
