The key difference lies in their underlying causes and the presence of nerve-root involvement. Radicular pain is due to nerve compression, while pseudoradicular pain results from non-nerve-related issues.Pseudoradicular pain, on the other hand, mimics radicular pain but is not caused by nerve root compression. Instead, it originates from structures like muscles, ligaments, or facet joints in the spine while Radicular pain is caused by the compression or irritation of a spinal nerve root, often due to conditions like herniated discs or spinal stenosis.
