Serratus anterior strain

A catch over the side ribs that hurts when you breathe deeply
Get help right away if
Call emergency services or go to A&E if you heard a crack when it happened, if the injured part has changed shape, if it has turned blue or grey, or if it feels numb.

Why it happens

Something has been overstretched or torn — here, the serratus anterior along the ribs. It happens when you overstretch or twist, and more easily if you did not warm up or it was already tired.

How it feels
- Pain, tenderness, or weakness
- Swelling or bruising
- Muscle cramping or spasms
- You cannot put weight on it or use it normally
How long it usually lasts

Most feel better after about 2 weeks. Avoid heavy exercise such as running for up to 8 weeks.

When to see a doctor

Get advice if severe pain is getting worse, if swelling or bruising is bad or worsening, if you cannot put weight on it or move it, or if you have a high temperature or feel shivery (that can mean infection).
