Could My Foot Be Seriously Injured After An Inversion Injury With Swelling, Bruising, And Pain On Standing?

Hi, I had a minor fall and I had a foot strain by inversion. The middle part of my left foot is swollen and bruised a bit. I feel a bit of numbness in that area, but no pain after 2 days, and numbness is gone too, but I cannot stand on foot without pain. I can move my ankle move my toes. I do not have posibility to go to doctor at all. Can you help?
