Botched Shot?

This doe has shown-up several times on more than one of the trail cameras.

What is curious is the blemish just behind the right forequarter.  Haven't been able to obtain a close-up but it is an obvious deformation of the skin on the animal.

I cannot help but wonder if it might be the consequence of a botched bow-shot.  A wound caused by a deflected arrow or poor shot placement?  Is it healed or is it festering?  From all outward appearances the animal appears healthy.  She has been mothering a fawn.

Wounded animals have been know to survive with broad heads remaining embedded in the flesh after the arrow shaft has been busted-off.

I wonder...
