Causes of sciatica pain
One common misconception about sciatica is that it’s consistently the result of a herniated disc. Contrary to what many people consider here’s another one, sciatica does no tinvolve issues with the sciatic nerve.
Annular irritated spinal nerve root and rip
Technically speaking, causes of sciatica pain caused by a herniated disc is called.
The nerve roots leave holes on both sides of the spinal column called the intervertebral foramen out.
Radiculopathy can happen when a herniated nucleus pulposus (the soft stuff usually situated on the interior of the disk) escapes out of the disk and presses on the spinal nerve origin. Typically, the nucleus pulposus moves through tears that appear in the outer fibers of the disk. Such tears are called annular tears.
Spinal stenosis means narrowing of spaces in the spinal column.
Frequently associated with age and/or arthritis, spinal stenosis is a narrowing of intervertebral foramen or the spinal canal. (The word stenosis is an overall term that refers to a narrowing.)
Kinds of Spinal Stenosis
Spinal stenosis comes in 2 main kinds: Central duct stenosis, where narrowing happens in the holes situated on the sides of the spinal column where the narrowing occurs in the spinal canal, and neuroforaminal stenosis.
Let us discuss central duct stenosis the spinal canal is the passageway that is centrally located down which the spinal cord passes.

With neuroformainal stenosis, the narrowing appears in the holes situated on the sides of the spinal column. Tissue that branches out from the spinal cord en-route to the remainder of your body becomes a nerve root and, upon additional branching, packages of fibers nerves are usually called by us. The nerves pass through these foramen (i.e., the holes) as they leave the spinal column. This, consequently, may irritate the spinal nerve root, resulting in sciatica-like symptoms.

The piriformis muscle is in addition to the sciatic nerve in the buttock.
Piriformis syndrome is a rare illness that can lead to sciatica-like symptoms. Unlike both of the other causes (i.e. stenosis and herniated disc as described previously) of one sided leg and/or buttock pain, piriformis syndrome-associated sciatica doesn’t originate in the spinal column. Because of this, it’s occasionally called “pseudo-sciatica.”
A buttock muscle – found over the sciatic nerve in the rear of the hip, and aptly named the piriforms – compresses this nerve, causing pain and symptoms that are electric in that same leg that buttock or down.
