Ever felt a sudden, sharp pain in your calf when sprinting or changing direction? That could be a calf strain — a really common injury in active people. Here’s the quick, clear breakdown.
What causes it?
Calf strains happen when the calf muscles are overstretched or contract forcefully, often during sprinting, jumping, or sudden changes of direction. Even a missed step or strong push-off can do it.
What’s actually happening?
The muscle fibres tear — sometimes tiny microtears, sometimes more serious damage. This leads to pain, swelling, bruising, and reduced strength.
• Mild: small tears, manageable pain
• Moderate: partial tear, noticeable swelling and weakness
• Severe: full rupture, significant pain and loss of function
Common signs
• Sudden sharp calf pain
• Swelling or bruising
• Pain when walking or pushing off
• Tightness or weakness
• Sometimes a “pop” at the moment of injury
Who’s most at risk?
Runners, jumping athletes, weekend warriors, older athletes, and anyone with tight calves or sudden spikes in training.
What to do next
Don’t push through it!!
Reduce load, avoid aggressive stretching, and get proper advice early.
The right rehab makes all the difference — not just for recovery, but for preventing it happening again.
