I doubt that, without access to your full medical history and an opportunity to examine you, even the mighty Sqad could provide a definitive answer here.
However it occurs to me that if it's at its worst during the day it might be heart-related. (i.e. it could be a precursor to the swollen ankles which are often asociated with a heart not functioning at its best).
If it's at its worst during the evening or at night though then it could be mild RLS:

(Note the 'creep crawly' feeling referred to there. It sounds very much like what you're describing).
