Intervertebral disc degeneration is a condition where the discs between the vertebrae in the spine lose their flexibility, elasticity, and cushioning ability. This degeneration can occur due to aging, wear and tear, or injury, leading to reduced disc height and potential pain. As the discs deteriorate, they may also bulge or herniate, which can put pressure on nearby nerves. Symptoms often include back pain, stiffness, and sometimes radiating pain in the legs or arms. Treatment options vary and may include physical therapy, medication, or, in severe cases, surgery.
