I Am 185 Lbs. About 50 Lbs. Overweight. I Was

I am 185 lbs. about 50 lbs. overweight. I was wearing smooth bottomed shoes. I was standing on a moderate incline. Not facing up or down the incline but sideways. I slide about 6 inches down the incline quickly. I came to a sudden stop when my foot fell into a shallow hole and Quickly bent underneath my ankle with a loud cracking sound. So painful I screamed at the top of my lungs. Was in extreme pain for about 10 minutes, then moderate pain for 30 minutes. Swelled up extremely big. Two weeks later still swelling up like an egg. Could the cracking noise have been a bone?
