Someone Hit My 'baby' Toe - Which Hurt ( Maybe

Someone hit my 'baby' toe - which hurt ( maybe broke??) but that evening - it began to bruise. The next day my entire foot is swollen and bruising has occurred on the inside of my ankle. I have tried to keep ice and elevate it. That helped for a day. Now back at work ( I sit at a desk -) I have tried to ice my foot and to keep it elevated - but it does not seem to help. Should I be concerned? or keep icing ?
