What is the connection between sciatica and nerve ending pain and slipped discs?

Radicular pain: Sciatica is a general term for radiculopathy involving the lower extremity usually resulting from a herniated disc that is irritating and or compressing a nerve root. It may also occur from bony compression such as facet arthrosis or spinal stenosis or even muscular compression, i.e., piriformis syndrome.

Related: Sciatica is simply pain down the back of your leg to below the knee. Most common cause is a herniated disc with a pinched (compressed) spinal nerve.

Back & Leg Pain: Sciatica is pain in the distribution of the leg as a result of an irritated nerve or facet joints or other injury typically in the lumbar spine (low back) which are caused by herniated disks, spinal stenosis or degenerative disc disease, etc requiring further evaluation by a spine specialist and may be candidate for facet injections/radiofrequency ablation and epidural steroid injection.
