Disc herniation can occur in any disc in the spine, but the two most common forms are lumbar disc herniation and cervical disc herniation. The former is the most common, causing low back pain (lumbago) and often leg pain as well, in which case it is commonly referred to as sciatica .
Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica. In this article, the term is used to describe a lumbar herniated disc.

There are three general types of low back pain by cause: mechanical back pain (including nonspecific musculoskeletal strains, herniated discs, compressed nerve roots, degenerative discs or joint disease, and broken vertebra), non-mechanical back pain (tumors, inflammatory conditions such as spondyloarthritis, and infections), and referred pain ...
The total height increase was 1.5 in (3.8 cm), measured at the end of the mission. This elongation is presumed to be due to the expansion of intervertebral discs during weightlessness (axial unloading). The astronaut also reported back pain on landing day that was associated with a herniated intervertebral disc.
The MSU Classification for herniated discs uses the proximity of the disc to the facet joint when measuring the size of a herniated disc. [7] Using the MSU Classification, a grade of 1, 2 or 3 can be used to describe the size of a herniated disc with 1 being the least severe and 3 being the most severe.

When a herniated disc is compressing the nerve roots, hemi- or partial-laminectomy or discectomy may be performed, in which the material compressing on the nerve is removed. [52] A multi-level laminectomy can be done to widen the spinal canal in the case of spinal stenosis.
