Back pain is pain in any region of the back. It is divided into neck pain (cervical), middle back pain (thoracic), lower back pain (lumbar) or coccydynia (tailbone or sacral pain) based on the segment affected.[1] The lumbar area is the most common area for pain, as it supports most of the weight in the upper body.[2] Episodes of back pain may be acute, sub-acute, or chronic depending on the duration.
