Pain triggered by the structures that form and make the spine function, such as the discs, vertebrae, facet joints, ligaments and/or paraspinal muscles located in the lower back.

Burning, tingling or prickling pain that starts in the lower back and travels through the buttock, thigh and leg, usually caused by compression of some nerves responsible for giving the sensitivity and mobility of the lower limbs.

The intervertebral discs are structures that separate the vertebrae and function as a shock absorber between them. A herniated disc occurs when there is an abnormal exit of the disc into the neural canal, where the nerves are stored, and this is irritated by the compression of the nerves.

The neural canal is the hole located between the vertebrae and is the place through which the spinal cord and the nerves that are generated from it and that go from the brain and are distributed to the arms, trunk and legs, the narrow channel occurs when the hole begins to decrease in size due to the presence of hernias, abnormal bone growth or growth of ligaments, thus causing compression and irritation of the spinal cord or nerves generating radiculopathy.

It is the forward displacement of a vertebra with reference to the vertebra just below it, this causes narrowing of the duct and symptoms that manifest themselves basically in the legs due to irritation of the lumbar nerves which give sensitivity and mobility to these. It most frequently affects the last two lumbar vertebrae.
