Upper back pain, also known as mid-back pain, is not as common as neck pain or low back pain. The thoracic spine—the upper or mid-back region—does not move as much as the cervical (neck) or lumbar (low back) spines, so there aren't as many injuries associated with overuse.

Oftentimes, patients with upper back pain also have neck pain. That's particularly true of patients whose upper back pain is caused by poor posture. Think of sitting hunched over as you work at your desk: Your upper back is rounded and your neck is straining forward at an unusual angle. Poor posture can lead to muscle strain or muscle fatigue, both causes of upper back pain.

This article series will cover other causes of upper back (mid-back) pain, and you'll learn about common treatment options to relieve your pain.
