Cervical disc herniation occurs when the soft inner material of a cervical disc in the neck bulges out through a tear in the outer layer. This can put pressure on nearby nerves or the spinal cord, leading to pain, numbness, or weakness in the arms, shoulders, or neck. Common causes include age-related wear and tear, injury, or repetitive strain. Treatment options may involve physical therapy, medications, or, in severe cases, surgery to relieve pressure and restore function. Understanding this condition is important for effective management and recovery.
