What causes pain in my fingers whenever they are exposed to sudden coldness?

I work at Domino's making pizza, and the toppings for the pizzas are usually kept very cold, sometimes almost frozen. Whenever I stick my hand in the really cold or frozen toppings, the sudden cold causes extreme pain in my whole fingers and finger joints, to the point where I can't even use them anymore and I have to stop until the pain resides. Normally, the cold doesn't affect my fingers like that, if it's gradual coldness like in cold weather or if I go into the walk-in freezer at work, and stand in there until my fingers get cold, I don't feel any pain from that. However, I do get a problem with my fingers if I go from being in cold weather until my fingers become really cold, into normal temperatures/warm temperature and my fingers defrost, my fingers start to burn a little and feel swollen and painful, even though they aren't visibly swollen, and it hurts to try to use any sort of utensils ( I mostly had this problem in school during the cold weather, when my fingers would become cold from standing outside waiting for class, until I finally entered the warm/room temperature classroom, I had problems using a pencil. ) I've always had that problem, though, but the pain from sudden coldness is new and feels different and worse. None of the other employees who make pizzas and stick their hands in the same cold topping experience this pain.What causes pain in my fingers whenever they are exposed to sudden coldness?
