“That’s where a lot of prayers come at it,” said one man. “That’s all I have.”

When asked where he’ll be sleeping tonight, one man said,”I’m going to East Liberty right now, to see if I can get lucky.”

Any exposed skin can get frostbite within minutes of being outside.

Damage from frostbite can range from superficial to deep.

“They do look like burns and that’s actually how we treat more frostbite – severe frostbite,” says Dr. David Ondrako, in Allegheny General Hospital’s Emergency Department.

First Degree Frostbite – or Frostnip, you can experience tingling, numbness, burning or itching. The affected areas may look white and there can be pain as the tissue re-warms.

In Second Degree Frostbite – blisters form. The skin looks waxy white or yellow in color and indicates deeper tissue injury.

With Third Degree Frostbite – damage is through all skin layers. Affected areas turn purplish blue and then black as tissue dies.

But even superficial frostbite can cause long term problems according to Dr. Ondrako.

“You can with neuropathy and other problems with the nerves below the skin,” he said.
