ANSWERS: 1
  • The spinal column is made up of several bones (vertebrae) with tough cartilage cushions (disks) between them. As the disks age, it is normal for them to "bulge" or go into the space where they once did not.

    Location of the L1-2 Disk

    L1 and L2 refer to the top two vertebrae of the lumbar region of the spine (lower back). The L1-2 disk is between those two vertebrae.

    Bulging vs. Herniated Disks

    According to the Mayo Clinic, bulging disks are fully intact, but are being squeezed between the vertebrae and therefor push outward. A herniated disk has broken through its outer cartilage so its softer insides come out.

    Significance

    Bulging disks are considered to be a normal condition as the body ages. They typically don't have any other symptoms other than the shape change.

    Misconception

    Some people mistakenly use the terms "bulging disk" and "herniated disk" interchangeably. This is misleading as a herniated disk is a much more serious condition.

    If You Have Pain

    If a bulging disk is causing pain by pinching the nerves, you might need anti-inflammatory medication, physical therapy or surgery.
