How will they treat my sore wrist?

As a nurse I would recommend heat not ice. you are most likely just sore because you are using muscles you do not normally use to that extent. you can also use a sports cream like ben gay. It is better that say icy hot. I would go to sports advisor tomorrow though. They will most likely have you have it x-rayed to make sure you did not fracture or break it. and most likely will give you a wrist support brace. you will be fine. nothing to be scared of at all. Good luck!
