I did that when I was about 7 at my Grandmothers house with her treadle. She and Moma had told me to be careful and there I sat with the needle in my pointer finger. I never said a word. Luckily my Aunt Alma was watching and slipped over and raised the needle out. We pulled it open and poured hydrogen peroxide in and through it LOL then put King Payne Salve on it and though it was sore a few days it got better. I think I could take pain better when I was younger and I went right back to sewing when they bandaged it up.
Hope it's better soon. With us being on the farm so much we always kept our tetnus shots up to date.
