I have done that two time, the first time I went to the hospital with the needle in my left thump. I was doing a quilt for my son and was doing the quilt all over when the bell rang and I jump and then the needle broke living half on the thump and half on the sewing machine, at the hospital they gave me shots to numb my thump and then they pull the needle out, the shot that the doctor gave me hurt more then the needle.
