I don't really know if the swelling went down between days 3 and 4, but bruising did start to emerge...
Here you can see how swollen I am under my chin...
I think the swelling has gone down some, maybe along my bottom jaw :)
I like that, in this picture, you can see how my chin isn't quite as out there :) though you can see the bruising.
And, lastly, a lovely shot of the bruising that began emerging around day 4 and got worse into day 5 :)
I'm going to see my OS in a few hours, so I'll have more to update you all on after that!
