Degenerative disc disease is a condition that occurs when the discs in the spine lose their cushioning ability over time. These discs act as shock absorbers between the vertebrae, and as they wear down, they can lead to pain, stiffness, and reduced mobility. This degeneration is often a natural part of aging but can also result from injury or repetitive stress. Symptoms of degenerative disc disease may include back pain that worsens with certain activities, numbness, or weakness in the legs. Treatment options vary and can include physical therapy, medications, or, in severe cases, surgery to relieve pressure on the nerves and restore function.
