So, four days ago I was bored in class that I placed a match inside a straw and pinned it with two thumbtacks. I got pricked by one underneath the fingernail and I'm not so sure if I'll be getting tetanus from that. I don't recall it being rusty since it was new, but I'm feeling really paranoid. It's just a small wound and I don't think there's a need to tell my parents because I've wounded myself with rusty metals before (I don't cut, I get them accidentally) and there was nothing to worry about, but my main concern is how will the wound heal underneath the nail? If I do tell my mom she'd get all paranoid and I don't want that.
