Degenerative Disc Disease is a common age-related condition where spinal discs lose their cushioning, flexibility, and height, often leading to pain or stiffness. It can result from aging, repetitive motion, injury, or genetics. While many people experience no symptoms, others may have neck or back pain, radiating limb discomfort, or numbness. Diagnosis typically involves a physical exam and imaging such as X-rays or MRI. Treatment often begins with rest, physical therapy, and medication. Surgery such as disc removal and spinal fusion is considered only if conservative care fails and nerve compression is present.
