Jumped off 7 feet ledge...landed on right heel?

Okay the story is i got locked out of my house and decided to go through my neighbor's front gate and clime the fence to my house. i jumped off the ledge into my back yard and i landed on my heel. when i landed i knew i landed wrong because i could feel my body going num for a little bit due to the impact of the land. its day 2 now and its hard for me to walk, i can stand on my heel but everytime i walk i walk on my toes and the heel is lifted alittle cause it hurts and i limp when i walk now. it is possible i only bruised it and not any worst? i havn't gone to the Doc. yet but i plan on going on day 4 if it doesnt change
