What is small of the back?

The small of the back, also known as the lumbar region, is the part of the spine that curves inward just above the buttocks. It consists of five vertebrae (L1-L5) and provides support for the upper body and transfers the weight to the pelvis and legs. The small of the back is prone to injury and pain due to its role in supporting the body's weight and movements. Common causes of pain in this area include muscle strain, ligament sprain, herniated disk, and degenerative disks. Exercises and stretches can help alleviate pain and prevent further injury to the small of the back.
