Degenerative discs意思
"Degenerative discs" refers to the degeneration or wearing down of the discs that are located between the vertebrae in the spine. These discs act as cushions, providing shock absorption and allowing for flexibility and movement. As people age, the discs can undergo degeneration, which can lead to a variety of symptoms and conditions, including back pain, sciatica, and reduced mobility. The process of degeneration can involve a loss of the disc's normal hydration, which makes them less flexible and more prone to tearing or herniation.
