I think i broke my bone, please help!?!

i was running outside on a lumpy field. i fell i little bit but didn't land quite right. i landed on my one foot, but with my knee locked(so my foot was perfectly straight). i think some how my bone where my thigh is somehow absorbed the small impact(don't know the name of the bone). i rested for a few minutes, then it started to fell better. but now it's been 30min, and it's throbing like crazy.
i've broken many bones in the past. this one doesn't feel like a crack. it just feels like one heck of a charlie horse. there's no swelling, my muscles don't seem to hurt, and the pain's pretty much the center of my thigh. there's no black and blue makes coming up towards the skin. but i'm still not sure if it's a break. any docters/nurses out there that can answer this problem.? thanks
if you need more info, i'll post that

p.s. hurts about the same sitting down, or standing with all weight on the one legHealth Question & Answer
