And Jeebus, what's with that baseball-sized bruise on the back of his right hand?

Nothing.

I have the same problem. While it doesn’t look nice, I live with it.
Long doctor explanation, but to put it in a nutshell it mainly was/is caused by
years of taking blood thinners due to heart problems. I bruise very easily, even at the
slightest bump.
Now I only take a baby aspirin once a day, but the condition is here to stay.

Other meds can also cause the same problem.
