Contusion Confusion

From where did this come,
this discolor, this bruise,
the one of which I have
no knowledge, I didn't choose?
From where did this tender
to the touch spot come,
this skin that's toughness
has been totally undone?
From where did the evidence
of a wound recently formed
have its genesis and exodus
onto a body where it's now adorned?
And when will it stop,
this pain brought on suddenly
in a sneak attack reminder
of a life gone through begrudgingly.
