I hit my toe really hard what can i do?

earlier today i made a dumb mistake of rushing up the stairs and i hit my toe straight on into a step. it isnt the big toe, it was the second one right next to the big toe on my left foot. it hurt but i just ignored it anyways after an hour it started to hurt a lot i cant walk on that foot. i cant move it even if i use my hand to move it it hurts really badly. i have sprianed my arm before and this is just worse. i know it isnt broken because it isnt out of shape, and there is no color change. so far i only feel numbness but pain when walking or trying to move it, and swelling. what can i do to help it feel better? how long will it take to heal?
