Strains and Sprains: What Is the Difference and What Should You Do First?

A sprain affects a ligament, which connects bones at a joint. A strain affects a muscle or tendon, which connects muscle to bone. Both can cause pain, swelling and difficulty moving, so how an injury feels does not reliably tell you which tissue is involved.¹ First, stop the activity, protect the area and check whether medical assessment is needed.

Whether you rolled an ankle during weekend sport or felt a sudden pull while lifting at home, the useful next step is to understand the injury before trying to train through it.

When medical care comes first

Seek urgent medical assessment if the limb looks deformed, you cannot use it or put weight on it, or pain is severe. Numbness or a cold, pale limb also needs urgent attention.² Do not try to straighten a suspected fracture or put a joint back into place. Call 000 for a medical emergency.

If you are unsure whether the injury is a fracture or dislocation, see a doctor. Healthdirect also advises medical review after first aid and when symptoms are not improving within a week.¹ That is not a reason to wait a week when the injury is worrying or getting worse.

The difference, without trying to diagnose yourself

Question	Sprain	Strain
Which tissue is affected?	A ligament supporting a joint	A muscle or tendon
A familiar example	An ankle twisted on an awkward landing	A hamstring injured during a sprint
What can you notice?	Pain, swelling, bruising or reduced movement	Pain, swelling, bruising or reduced movement

The shared symptoms are why this table is an explanation, not a diagnostic checklist.¹ A bruise does not tell you the injury’s grade, and being able to move does not settle whether a fracture is present.

What should you do first?

For a suspected acute soft-tissue injury, Australian first-aid guidance uses RICER: rest, ice, compression, elevation and referral.³

• Rest and protect: stop the activity and support the injured area. Avoid loading it while arranging assessment.
• Ice: wrap a cold pack in a cloth; do not apply it directly to skin. Better Health Channel advises 20 minutes every two hours during the first 48-72 hours.
• Compression: use a firm elastic bandage, without restricting circulation. Seek help if you are unsure how to apply it.
• Elevation: raise the injured area above heart level where practical.
• Referral: arrange medical assessment to clarify the injury and the next steps.³

In the early period, avoid heat, alcohol, running or other aggravating activity, and massage of the injured area.³ First aid supports the immediate response; it does not confirm the diagnosis or clear you to resume sport.

These points concern a new injury. They are not an instruction to stop all movement indefinitely, or a treatment plan for persistent back or neck pain.

What to tell the practitioner

An assessment starts with how the injury happened and checks movement, strength and the affected tissues; imaging may be considered when clinically needed.¹ You can make the conversation more useful by noting:

• the movement, fall or impact involved;
• whether you could continue the activity;
• when swelling or bruising appeared;
• what you can and cannot do now;
• previous injuries and any first aid already used; and
• the activity you want to return to.

For example, “I twisted my ankle yesterday, stopped playing and still cannot walk normally” is more useful than simply asking for treatment for a sprain. You do not need to decide the diagnosis before the appointment.

Moving from first aid to recovery

Ask the clinician what you can do now, what needs temporary modification and what should trigger another review. A return to work may involve different demands from a return to running or a contact sport.

There is no single recovery date that applies to every strain or sprain. A plan should account for the injury, your current function and the activity you are returning to. Ask for clear milestones rather than relying on a fixed number of days.

Useful questions include: “What movement can I start with?”, “What changes mean I should stop?” and “When should we reassess?” A physiotherapist or other appropriate clinician may be involved in rehabilitation.

Where a chiropractic assessment may fit

Our muscle strains and sprains page describes related musculoskeletal concerns. At our Chatswood clinic, an assessment can consider whether chiropractic care is appropriate for your circumstances. Suspected fractures, dislocations and significant injuries need medical care first.

For the broader context, read Sports Injuries: Assessment, Recovery and Returning to Activity in Chatswood. Our what to expect page explains the appointment process. Once urgent concerns have been addressed, you can book an assessment to discuss suitability and next steps.

Common questions

Can I tell whether it is a strain or sprain from the pain?

Not reliably. The tissues differ, but symptoms overlap. Assessment is more useful than choosing a label from a list of symptoms.

Does every injury need an X-ray?

No. A clinician decides whether imaging is needed from the history and findings. Ask what the test would clarify and whether it would change management.

Can I massage a newly injured muscle?

Avoid massaging the injured area in the early first-aid period.³ Ask when soft-tissue work or other management would be appropriate for the assessed injury.

Can I play again once the swelling settles?

Settled swelling alone does not establish readiness. Discuss the movements and loads your sport requires, and the milestones for returning.

What this guide cannot tell you

This article cannot diagnose an injury, exclude a fracture or decide your return-to-sport date. Its warning signs are not exhaustive. If the injury is severe, worsening or uncertain, seek medical advice rather than using the article to delay care.
