I Dropped A Heavy Framed Mirror Straight Down Onto The

I dropped a heavy framed mirror straight down onto the top portion of the middle of my foot. I have it elevated and ice on it now. It swelled up pretty big immediately but the ice seems to helping with that. I can still stand and put some weight on it, but it it pretty painful still. I have some slight numbing and pain in my toes and near the ball of my foot...but the object did not hit near the toes at all. I took some ibuprofen as well. Is there anything else I need to do? How long should I keep ice on it? What about after the swelling subsides? Please advise. Thank you.
