Strain or Sprain? How to Tell the Difference
Sprains affect ligaments; strains affect muscles or tendons. Learn the difference, sensible early care and when an injury needs assessment.

A strain and a sprain can feel remarkably similar. Both can hurt, swell and make it difficult to use the injured area normally.
Sprain or strain: what is the difference?
A sprain involves a ligament — tissue that helps connect and support a joint. A strain involves a muscle or tendon. More than one structure can be injured at the same time, so the label is not always obvious from symptoms alone.
Pain, tenderness, weakness, swelling and reduced movement can occur with either injury. What matters more than self-diagnosing from one symptom is how the injury happened, how well you can use the area and whether it is settling.
Sensible early care
For the first couple of days, protect the area from activities that clearly aggravate it. Relative rest does not mean becoming completely inactive: gentle movement within comfort is often useful. A cold pack wrapped in a towel may help pain and swelling for some people.
When an injury needs urgent assessment
Seek urgent medical help if you heard a crack, the area has changed shape, you cannot use or bear weight through it, or there is numbness, pins and needles, marked colour change or coldness beyond the injury.
How osteopathic care can help
Once a serious injury has been excluded, an osteopathic assessment can look at the injured area and how the joints and muscles around it are moving. Depending on the presentation, care may include hands-on treatment, individual exercises, movement and rehabilitation advice, and a graded return to activity where appropriate. If the injury needs imaging, medical assessment or input from another healthcare professional, I’ll explain that and help point you towards the appropriate next step.
