Todd - a cast makes a huge difference! Gets the pain down to a dull roar. I've fractured a few bones, one of which was my tibia just below the knee. For a reason I can't remember, they weren't able to cast it. So I spent weeks in a brace, being very still.
As much as broken bones hurt, dislocations do indeed hurt much worse. Once I dislocate a toe and my unthinking reaction was to reach down and grab my foot. I jammed the toe back into place. Good God, did that hurt! I really don't want to imagine how a dislocated ankle feels.
I'm glad to hear you are through the initial hurt. It is all downhill now. At least until the cast comes off!
