Help, I think my toe maybe infected?

so, long story short….i was walking out of the gym,a week ago today, and happen to drop my umbrella on my toe and it took a chunk of skin off. My toe hasnt been able to heal and today it started feeling numb. does anyone know a good way for me to take care of that without having to go to the doctor, or would be best to just suck it up and go see someone.
