What is psoas syndrome?

Psoas syndrome is painful irritation or an injury in one of your psoas muscles. Healthcare providers sometimes call psoas syndrome iliopsoas syndrome. Psoas is pronounced SO-ezz.

The psoae (the plural form of psoas) are a pair of long muscles that run from your lower back to the top of your hips on either side of your spine.

Psoas syndrome causes pain in your lower back, hips or groin. Visit a healthcare provider if you’re experiencing pain that doesn’t get better in a week.

How common is psoas syndrome?

Psoas syndrome is rare. Many people who have it never get it diagnosed because symptoms usually get better before they visit a healthcare provider.

Experts think psoas syndrome is often misdiagnosed or underdiagnosed because it shares so many symptoms with other injuries or health conditions. The good news is that, in most cases, the same treatments that manage other, similar issues also treat psoas syndrome.

Psoas syndrome can cause pain in your back, groin, hips and butt.
