A herniated disc, also known as a slipped disc or disc prolapse, occurs when the soft inner portion of a spinal disc protrudes through a crack in the tough outer layer. This condition can cause pain, numbness, and weakness in the area where the affected disc is located. The most common sites for herniated discs are the lower back and neck. Treatment options include rest, pain management techniques, physical therapy, and in some cases, surgery. It is important to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.
