Mid back pain is one of the more common complaints patients report when initially visiting a chiropractor. The mid back area is commonly referred to as the thoracic spine. The thoracic spine consists of twelve vertebra attached by twelve pairs of ribs that make up the mid back area.
Most patients complain of mid back pain with limited motion in the thoracic region due to excessive twisting/bending of their torso or the pain in the region between their shoulder blades. Symptoms of mid back pain can range from muscle tightness and spasms, trigger points (area of acute spasm and pain), restricted range of motion when bending or twisting, sharp or stabbing pains from the back, radiating to the front of the chest or abdomen. The rib cage can also become irritated/misaligned causing symptoms that mimic respiratory or cardiac problems such as shortness of breath, irregular heart beat and fast or slow heart rhythms.

The mid back area is highly reactive and compensates for the pelvis and lower back region (lumbar spine) or to the upper neck area (cervical spine). Sitting at a computer with improper posture or driving for long periods of time without a lumbar support are two common causes of mid back related pain. Mid back pain can also be associated with a referred pain or complication from one of the organ systems in the thorax such as the liver, gallbladder or kidneys. Some common causes of mid back pain are:

Mid back injury
Rib injury
Muscle sprain/strain
Excessive exertion
Excessive lifting
Gallbladder conditions
heart conditions
lung conditions
Peptic ulcers
Kidney infection
