Can someone give me a better idea on treating my swollen foot?

I was at my friend's pool party and i jumped of the wooden deck but somehow i miraculously got my foot stuck in the gap between the wooden deck and the plastic outer rim of the pool. I then twisted my body to the left to pull my foot out of there before i break my ankle and i ended up with a really bad swollen bruise on the right side of my right foot. So i put a pack of ice on it and the swollen bruise sank down a lot and i could walk again. Then i decided to wrap my foot around with a cold foot bandage, and decided it will be better by tomorrow. Then i drove home and i went to sleep for the rest of the day and i woke up and now the whole top of my foot is like completely swollen. i can't even bend my toes anymore because the bulge is in the way and i could barely walk. The condition is like worse than before. Can someone give me a better idea on treating this? Or should i just go to my doctor?
