Degenerative disc disease

Degenerative disc disease is not truly a disease. It is a term for the wear-related changes in the spinal discs that come with age. As discs lose water and height, they cushion the spine less well, and in some people these changes contribute to back or neck pain. Many people whose imaging shows disc degeneration have no pain at all.

• A dull, aching pain in the low back or neck, sometimes spreading to the buttocks, hips, or shoulders
• Pain that worsens with sitting or standing in one position, bending, lifting, or twisting
• Pain that eases with walking, changing positions, or lying down
• Stiffness in the morning that loosens up during the day
• Flare-ups of more intense pain that settle over days to weeks

If a worn disc narrows the space around a nerve, there may also be pain, numbness, or tingling down an arm or leg.

Discs naturally dry out and become less flexible over time. Small tears in the outer ring and loss of disc height are part of normal aging, and they can lead to related changes such as facet joint arthritis, bone spurs, and spinal stenosis.

Factors associated with faster or more painful degeneration include:

• Family history (genetics)
• Smoking
• Excess body weight
• Heavy physical work or repeated lifting and twisting
• A previous back or neck injury

Diagnosis is based on a history and physical examination. X-rays can show narrowed disc spaces and bone spurs, and an MRI shows disc hydration, tears, and any pressure on nerves.

Because disc changes are so common on imaging in people without pain, scan findings are always interpreted alongside your symptoms and examination. Pinpointing a single disc as the source of pain can be difficult, and other structures, including joints, muscles, and nerves, may be involved.

Treatment focuses on managing pain and keeping you active; no treatment reverses disc wear. Non-surgical care is the foundation for most people and often combines several of these:

• Staying active, with physical therapy focused on core strength, flexibility, and posture
• Low-impact aerobic exercise such as walking, cycling, or swimming
• Heat or ice, and over-the-counter or prescription medications when appropriate
• Weight management and quitting smoking
• Pain-coping approaches such as cognitive behavioral therapy, often combined with exercise
• Injections in selected cases, such as an epidural steroid injection when nerve pain is present

Surgery is considered for a small number of people whose pain remains disabling after a thorough course of non-surgical care, or when degeneration causes nerve compression, instability, or deformity. Options may include spinal fusion or, for selected patients, artificial disc replacement. Surgery for back pain alone, without nerve compression, is a careful, individualized decision; your surgeon will discuss its potential benefits, risks, and limits for your situation.

Disc-related pain often comes and goes. Flare-ups usually settle with a short break from aggravating activities, gentle movement, and a gradual return to exercise. A regular home exercise program and good body mechanics are part of long-term management. Recovery after surgery depends on the procedure and is guided by your surgical team.

Disc aging cannot be stopped, but these habits support spine health:

• Exercise regularly, including core and back strengthening
• Maintain a healthy weight
• Don't smoke
• Use good lifting technique and avoid staying in one position for long periods
