Like other types of nerve pain, sciatica can cause sensations that can be challenging to describe. Sometimes, people with sciatic nerve pain refer to it as a burning pain or a deep ache, Delaney says.

Also called sciatica, or lumbar radiculopathy, it's described as a "radiating pain" that travels from the sciatic nerve, located in the lower spine, down the back of your thigh.

When the sciatic nerve is pinched, it can lead to symptoms of pain, burning or numbness. Often during an episode of sciatica, the common response is to go on bed rest.

In contrast, sciatic nerve palsy, presenting as equinovarus or equinus deformity, was diagnosed on average 3.8 months after the intragluteal injections (Napiontek & Ruszkowski, 1993).
