I sewed my finger with a treadle machine when I was about 14 and broke a neadle in my finger once had to pull it out, but my husband takes the cake.
he cut of the sides of 2 fingers with a stanley knife and it took months to heal properly, another time he sliced the side of his index finger and it healed with a lump, a few months later he did it again and took the lump of now it has healed without a lump, but when i rang emergency and told them i was bringing in my husband as he had sliced the side of his finger of she said don't come in till after 5PM as the doctor won't be here before that to stitch i told her there was nothing left to stitch, so i took him in to get it dressed and she said your right there's nothing left, that took ages to heal. he has been in er so many times they all greet him by name
