A little over a month ago I jumped a fence to run on a closed off track but fell awkwardly on my heel from 5 feet. For the next 4 or 5 days there was considerable pain and I walked with a limp. I took about 2 weeks off from running however the pain didn't subside completely. I started running again only because it doesn't hurt while doing so, (it hurts more to walk because im putting more weight on the heel). The injury is tender to touch, any idea what the problem is? More likely a heel bruise or a stress fracture?
