Back pain
Refers to back pain. Based on the affected segment, it is classified as neck pain (cervical), middle back pain (thoracic), low back pain (lumbar), or coccydynia (tailbone or sacral pain). As it supports most of the upper body's weight, the lumbar region is the most common location for pain. Depending on duration, back pain episodes may be acute, subacute, or chronic. The pain may manifest as a dull ache, a shooting or penetrating pain, or a burning sensation. In addition to the legs and feet, discomfort can spread to the arms and hands, and may manifest as numbness or weakness in the legs and arms. The back is the large posterior region of the human body, extending from the buttocks to the back of the neck and the shoulders. It is the opposite side of the body from the chest. The vertebral column, which runs the length of the back, forms a central depression. The shoulders at the top and the pelvis at the bottom create the width of the back.
