Topical NSAIDs are increasingly being used due to their minimisation of systemic effects . It has been found that plasma concentrations after topical administration are as low as 5 % of the plasma levels of oral NSAIDs , resulting in a greatly reduced side-effect profile , and should therefore be recommended . 25
Oral opioids should rarely be used , unless for severe pain , due to their potential gastrointestinal and neurological side effects , and addictive properties . 23
A recent meta-analysis found a lack of difference in analgesic efficacy between NSAIDs and paracetamol or NSAIDs and opioids for acute soft tissue injuries . 23
However , NSAIDs were associated with increased gastrointestinal side effects relative to paracetamol , but with fewer adverse events and better functioning than opioid-containing medications

Return to exercise Due to the wide range of muscular injuries , no ‘ one size fits all ’ approach exists . Once a musculoskeletal injury has occurred , the main goals should be to return to exercise in a timely fashion , and minimise the risks of re-injury by completing rehabilitation in a step-wise fashion . 11
Returning to exercise should be guided by the severity of the injury , the healing process , patient and activity factors , and ideally , by a practitioner experienced in rehabilitation .
Universally , each patient must be allowed adequate time for the inflammatory and reparative phases to occur . Therefore it is important that practitioners deliver sound advice and education during this time to reduce injury , and maximise functional outcome . During the maturation / remodelling phase , the patient should be progressed through a stepwise rehabilitation program that incorporates multiple stages , as shown in figure 2 .
Initially , the patient should build up to pre-injury range of motion with exercises to maintain muscular power and proprioception .
Once this has been achieved without pain , it is often tempting for the patient to return to pre-injury exercise , but this is not recommended . At this stage , the patient should resume controlled activity including whole-body exercise , building up to specific return-toactivity requirements such as increased speed , agility , and sports-specific fitness and skills .
Once the patient has reached sustained activityspecific exercise in a practice or training environment , their return to exercise should then be considered .
Sports clinicians ( for example , sports physicians , exercise physiologists , and physiotherapists ) are welltrained to deliver personalised advice on appropriate interventions , exercises , and guided return-to-exercise . ● Dr Wheeler is a medical officer at SA Health .
