Over about two hours my feet slowly became very red and hot, I wouldn't say painful but uncomfortable and felt slightly swollen when I walked around.. Spread from my toes to my whole foot. The left foot was redder and it took a few hours to fade and only be slightly red but still visible. I have had raynauds symptoms in the past believed to be caused by an unknown condition, but this is very different than what I had before and was not triggered by cold.
