Lower Back Pain by Dr. Scott Katzman, MD As people age, bone strength and muscle elasticity and tone tend to decrease. The lumbar discs begin to lose fluid and flexibility, which decreases their ability to cushion the vertebrae. If the spine becomes overly strained or compressed, a disc may rupture or bulge outward. This rupture may put pressure on one of the more than 50 nerves rooted to the spinal cord that control body movements and transmit signals from the body to the brain. When these nerve roots become compressed or irritated, lower back pain results.
