I hurt my foot really bad. Do you think I should go to the ER?

I was playing around, I kicked something, and now my foot hurts like crazy. I have to hop, and even when I do that my foot hurts. I can barely feel my pinkie toe, and 3 of my other toes are hurting. I tried ice, and it helped for a little bit, but then it just got worse. What do you think I should do at home, and do you think I should go to the doctor or and ER?
