Oh I have done that too, but...
It was late at night, burning the midnight oil when the kiddies were 12 and under. Sewed my forefinger right through the nail, left hand--ouch--broke the needle, and I knew there was a pieceof needle in my finger. DH took me to ER, and the older MD on call didn't beleive me when I told him there was metal in my finger, but I could feel it. Long story short, he deadened the finger and started cutting and voila, there was about a 1/4" piece of needle. Think the old guy was wondering why any sane person was sewing at that time of night, but young mom's everywhere know why. Anyway 25+ years later end of finger still has a dead spot! Be careful out there!
