I have fractured mine twice but it was very painful when it happened, I fell down three steps the first time, the second time I was walking my dogs and slipped on hard smooth clay at a new pond edge as the dogs had made it wet running on and out.
I could not sit properly for almost 18 months both times and it delayed my mare being backed by 18 months, as I could not play soccer properly for about the same time.
It was painful to stand up too.
