Frostbite

This technically doesn't fall under the topic of "burns," but it was the closest thing that frostbite could apply to. If this can be redirected to a different forum or expert, I would appreciate that help.

Recently, I traveled to Green Bay to see a football game. The weather was roughly -25 degrees after wind chill. I dressed appropriately, but had my hands exposed for about 10 minutes while I had something to eat. After my hands went completely numb, I immediately to warm them up in my car, but some of my fingertips were still numb. After I got home, I soaked my fingers in warm water and waited for the feeling to come back. They feel better, but I still have little feeling in some of my fingertips and some tingling. There was/is no discoloration of the skin, but it does feel harder than the skin of my other fingertips. The part I don't get is that even though it they were extremely cold conditions, I only had my hands exposed for about 10 minutes. The rest of my family regained the feeling in their hands after a day or so, and there were so many other people that I saw walking around and eating without gloves and in less clothes than me. I thought they were crazy, but here I am as the one without full sensation in his fingers. Will the feeling eventually return and is there anything I can do to remedy this?
