take care of that Splave I know a few lads that lost fingers, toes, noses and other things not to be discussed from frostbite. If your skin turns rock hard you're beyond just minor frostbite.

Symptoms
Symptoms vary with the depth and amount of tissue frozen. Shallow frostbite results in a numb white patch of skin that peels after warming. Slightly deeper frostbite causes blisters and swelling of the affected area. Deeper freezing causes the extremity to feel numb, cold, and hard. The area is pale and cold. Blisters often appear. Blisters filled with clear fluid indicate milder damage than do blisters filled with blood-stained fluid.
