Thoracic back pain is common in people of all ages, mostly due to poor posture or heavy lifting affecting the joints between the vertebrae and ribs. The other conditions affecting the thoracic spine tend to be different from the ones affecting the lumbar spine.
UPPER BACK
Definition: Upper back pain occurs in the thoracic spine, which is often described as the upper back, middle back, or mid-back. Given the strength and stability of the thoracic spine, upper back pain is not as common as lower back pain, although it can be quite painful when it does occur, often in conjunction with neck pain or shoulder pain.
