Replying to Toenail issues

So, I fucked up my big toe like a month ago but it hasn’t started to fall off till I banged it again today on a jump. So my friend has had two fall off this season and said pull it out or just let it fall but idk. You see, it’s still connected pretty good to one said and the blue spot doesn’t reach it there. If u need a photo I can send it but I thought I wouldn’t add it in case someone is eating lunch. I know this is a common injury, but I wanna be safe since it’s still connected to part of it
