Hockey foot pains, not sure if it's cramps, been playing with no problems for years, still young.?

I've been playing hockey for over 10 years, I am 19 so it's definitely not an aging problem or out of shape problem. Just recently when I take off my skates, I have tremendous pain in the bottoms of my feet, I cannot put any pressure on them for at least 15 minutes, and have a hard time walking for the ensuing hours. I've been using the same skates for over a year, and haven't been off hockey for a long period of time. Anyone have any advice? Tying my skates looser is not really an option, it would completely throw my game off, plus I have a very weak ankle I need to protect.
