I'm probably not typical because mine was triggered by high doses of COPD meds, so I hope other people will chime in tomorrow, Sundays can be slow.

For me it had something to do with how much I was on my feet during the day but more than that from the heat from wearing shoes and the blankets at night. I got some relief from always going barefoot in the house and from sleeping with my feet outside of the covers, it seemed to be cumulative and add up if they got hot. That probably wouldn't work for everyone as some people are triggered by any temperature change.

I hope you get some responses from the gurus and find some relief.
