If it makes you feel any better I am currently healing from the exact same wound. It happened so fast, I don't even know how I did it. Not only did it go deep into my fingernail...the needle broke and angled the end that was embedded in my fingernail. I was home by myself and it was stuck in there so bad I had to get a pair of needlenose pliers to remove it. That was painful, and made me nauseous. It was stubborn and quite difficult to remove. I have been sewing for a long time and have never done such a thing. I felt like an idiot.
