Foot issue, sort of

Last few days, I keep getting this warm feeling on my feet. It's only in one spot at a time - at the moment it's on the outside of my right food, this morning it was on the top of my left foot, last night it was on the arch of my right foot. It's not painful, just a pleasant warm feeling, like I'm holding a warm cloth to my foot and it goes away in a couple hours. No discoloration, no swelling or itching, just this weird warm sensation.
Overall as weird symptoms go, I'll take this over all the rest, but I wondered if any of you have experienced this or am I just losing my mind? I did a search online but the only things that came up were for burning sensations, and it's definitely not burning.
Thanks!
