Could my ankle be broken?

so about three week ago i was jogging on uneven ground and rolled my ankle. I stepped in a small rut and fell pretty hard. i was in the middle of nowhere in the hills so i had to jog back four miles to my car. when i got home i elevated and iced it. i was able to walk on it but had to limp and put very little weight on it. its been almost four weeks and it is still swollen. I can move it and put weight on it but it pops and the back of my foot and "sprain" area is numb. It has been numb since i fell on it. There was very little bruising. Only for a few days and it was a greenish yellow bruise. It is not as sensitive and doesn't hurt as much but it is taking much longer than i expected. the numbness and swelling is also freaking me out a little. i have not gone to the doctor because i don't have insurance. can anyone tell me if this could be broken or why i might be numb?
