How To Treat Bump And Swelling On Top Of Foot?

Hi
I have kicked a door with the ball if my foot. 3 minutes later I could not walk on that foot at all. Less than 24hrs, swelling immediately but no bruising showed until later on. It was sore and felt exhausted, like how muscles feel after running a marathon or after snowboarding, extremely tight and weak and exhausted, but now there i swelling. I have a bump(occurred instantly after impact),but now it has been a little over 24hrs and still the bump on the top of my foot, sweeping has gone down but I still cannot put full weight on my toes and the balls of my foot. I've been putting weight on the outside when I need to walk. Seeing a doctor tmrw, been icing it and it's been elevated.
