By that point my shoulder was starting to throb a bit, so I went in the tack room to take a look at it. She managed to break the skin in a couple spots while biting thru a long sleeved t-shirt, sweatshirt, and vest. It was already starting to bruise and had swollen up. Unfortunately I like to sleep on my side so I didn't get much sleep Tuesday night. Wednesday I was pretty sore, but made it into work where a couple of my coworkers turned green when they saw it.
