Interesting. ‘Julese’ just talked about cold feet.
I’m suspicious that a have some vascular issues.
I appreciate you sharing your experience.
I’ll look for a foam roller (or get my lower legs massaged). I’m assuming you use an upward motion (from ankle to knee?).
Last winter I put in an electric blanket with a foot zone. I’m not a fan of electric blankets but making the foot of the bed warm (then turning it off) was helpful.

Thank you
