Sciatica is pain in the leg due to trouble in the back. The pain can be vexing because it frequently masquerades as a pulled muscle, as if a twine was pulled too tight through the rear of the leg. The leg appears to crave extending and trembling out, as if the muscles want unknotting.

The sciatic nerve is made up smaller nerve rootlets that leave either side of the spinal column through short bony ducts between L1 and the sacrum. They could be undermined by excessive long-term compaction of the lumber sections and by bloating of the facet joint capsule, the intervertebral disc, or both. The latter happens when there’s pathology of either structure.

The Basis For Sciatica Back Pain Is Either Bloated Facet Joint Or Intervertebral Disk

Sciatica can be a referred pain from an sad facet joint, or pain due to direct inflammation of a nerve root. Of the two, sent sciatic pain is considerably more common.

Referred pain is like a case of mistaken identity, where structures sharing the exact same nerve supply sense the pain too. The pain of a heart attack, for instance, on the left side of the torso and running down the left arm is another instance of referred pain.

Less serious (long-term) sciatica typically shows as back of knee pain, always due to an inflamed facet joint in the backbone.

In treatment for sciatic pain, sent leg pain is much simpler to cope with than accurate sciatica or radiculitis caused direct inflammation of the nerve itself. Extreme sciatica is a more intense pain, usually due to a prolapsed intervertebral disc.

Radiculitis is the result of a pathological intervertebral disc bulge applying pressure on a nearby nerve root and creating a noxious inflammatory climate. The cocktail of discomfort is both physical and chemical as the nerve is scalded by the ill disk leaking out inflammatory products. Broadly speaking, the more intense and the wider the spread of sciatic pain, the more intense the inflammatory focus in the back.
