A herniated disc (also referred to as a protruding or extruded disc)
is a condition where a portion of the gel-like center of the disc has
migrated through the layers of the annulus fibrosus. This can cause
mechanical pressure on neighboring structures and trigger chemical
reactions resulting in pain and inflammation. These changes will
often irritate the nerves, producing numbness or tingling in the legs
or feet. Left untreated, this condition may result in life-changing pain
and physical disability.
— What is Degenerative Disc Disease?
Degenerative disc disease is a state of dehydration and
deterioration marked by the gradual erosion of the discs ability to
distribute and resist mechanical loads. As discs deteriorate, they
become more prone to injury from physical stress. Degenerative
disc disease may also play a contributing role in conditions such as
disc bulges, disc herniations, and stenosis.
— What is Facet syndrome?
Facets are the posterior joints of the spine that
aid in keeping the vertebrae aligned. Facet syndrome can result
from injury or degeneration of the disc and is characterized by
pain, stiffness, and inflammation. The pain generally increases
with motion and is relieved by rest.
— What is Sciatica?
Sciatica is a condition often associated with a herniated or ruptured disc. When the injured disc compresses one of the spinal nerves leading to the sciatic nerve, it can produce a shock-like pain that travels through the buttocks and down one leg to below the knee. Tingling and numbness are common in this condition. Sciatica can occur suddenly, or develop gradually. The pain and symptoms of sciatica can be intensified by coughing, sneezing, or sitting in the same position for prolonged periods of time.
