Differences between radicular and referred pain

What are the differences between radicular and referred pain? 

The key feature of radicular pain is hot, electric sensations that radiate in the territory of the affected nerve root.

The pain will be sharp, shooting, and burning. The pain radiates down the limb but never up.

Sensory loss is rarely complete due to overlapping of other roots. 

Referred pain is a phenomenon that occurs when irritated or injured tissues (e.g., muscle, facet joint, or periosteum) cause pain that is perceived in a dermatomal distribution.

This pain may be shooting but is typically not hot or electrical as in radicular pain.
