Sprains and strains: Signs and symptoms

Recognizing sprains and strains
Since sprains and strains can be managed relatively simply, it helps to know how to identify this common type of soft tissue injury.1,2

Signs and symptoms
Both sprains and strains can cause pain, inflammation, and swelling.
- Symptoms of a sprain occur around the affected joint and can include bruising, loss of function, and mechanical instability if severe3
- Symptoms of a strain affect the injured muscle and can include spasm, weakness, and cramping3
- Symptom severity depends on both the severity of the injury and the time since the injury took place — it can take up to 24 hours for bruising and swelling to appear3
