How cold does it have to be to get frostbite/nip?

I live in Chicago and I dog walk for a living. Some may know already that we are freezing over here in windchills between -5 and -30. I make sure I bundle really well but I ride my bike for work too so I am always cold. The last couple of days my big toes have been in so much pain on my way home that I want to scream. The nails look a little greyish when I first take off my boots but then return to normal after a while. I feel like I am being dramatic though so I am just wondering if this is something i should be serious about or not + what can I do, I already wear 2 pairs of socks w/ winter boots?

As long as they return to normal its just really cold. You'll know if you ever get frostbite - its painful to touch even after hours inside and then it starts peeling and all that -lol almost like sunburn really. Maybe get new boots lol, because some shoes will contain the warmth generated by your feet better than others.

It doesn't take long in this frigid weather,add in the wind chill,its even less time. I would see my Doctor,its impossible for you to know or any other person to know for sure especially here.Take care. SW RNP
