There’s a solid chance you’ve tweaked your back before - after all, it's estimated 70-90% of Australians experience some kind of back pain at one point or another in their lives. Usually, it happens in the lower back, rather than the upper back. There’s a reason for that: “The rib cage offers a lot of support and stabilises the spine in the upper back,” says orthopaedic spine surgeon Dr Jeffrey Goldstein. “You don’t have similar support in the neck or lower back.” But just because these parts of the spine are more prone to feeling pain, that doesn’t mean the upper spine (also called the thoracic spine) is in the clear. Here are all the ways upper back pain can creep into your life.
