How do I recognise the difference between muscle pain and an injury?

Ordinary muscle pain often only occurs after a new or more strenuous physical activity and usually subsides within a few days. An injury can develop suddenly or gradually. Pain alone does not provide a definitive diagnosis. Seek medical advice if you experience significant swelling, a clear loss of strength, an inability to put weight on the affected area, or persistent or worsening symptoms.

What are the benefits of foam rolling?

Foam rolling can feel pleasant in the short term and improve range of motion. There is no evidence to suggest that it speeds up recovery from every injury. Apply a level of pressure that you can comfortably tolerate, and do not treat any acutely painful or injured area without appropriate advice.
