When I get angry I usually throw things & break things that way rather than breaking myself......that isn't a good thing either, but at least it doesn't hurt as much.

I have broken a finger once....I was holding onto the reins of a horse & he reared. I looked at my finger & it was completely crooked. I took it & snapped it once & it still wasn't right, so I snapped it again....it was finally straight.....then I passed out.

Later that day, I went to my orthopedic surgeon & he checked my finger...I had actually set it myself so he didn't have to do anything to hurt it more. From that experience, I know the pain you are experiencing.....hope it gets better soon.
