Chronic low back pain, however, ranges from annoying to debilitating. The vertebrae labeled L1 through L5 make up the lumbar region of your spine. They’re located from your hips up to the bottom of your ribcage. This area of your spine is known for: - These vertebrae are larger than those in the cervical and thoracic spine. - They support most of the weight from the upper parts of your body. - Round, rubbery pads, called discs, sit between the lower back bones and act as shock absorbers so you can move freely without bones rubbing against each other.
