OUCH! I hope it gets better soon!! These posts all brought back a memory from about 45 years ago, when I was in high school. My mom and I were both sewing and I got my finger under the needle. I very strongly shouted the "SH" word. (I grew up in a home where absolutely NO swearing was tolerated.) My precious mother very calmly looked over at me and quietly said, "Lin, is something wrong?".
Didn't need a tetanus shot--I tended to stay current on those during my growing-up years.
