Pain!

*PLEASE NO JOKES ABOUT THIS* So last night there were tornadoes and stuff near me well in an attempt to get my animals in the storm shelter with me (not a public one) i fell. I fell off or the steps to the house and wasn't even on the bottom one but my foot slipped and I landed on my butt (obviously). I only fell on one side though and now it really hurts! There is no bruise but yet I can't walk without pain and I can't touch it either! Will the soreness go away soon? It just worried me because I thought it would be a giant bruise that would go away soon but it's not bruised which could mean it did something internally and not just on the surface! HELP!
