I've had two toenails come off on my left foot new ones growing underneath then about six months later a toenail came off on my right foot with a new nail underneath they are lovely toenails. Don't know why this is happening I'm not very active.

Omg this happened to me! My mum was cutting my toenail when I was like 7 and she accidently caught the skin, I jerked and the toenail came off and another perfectly fine toenail was there, wtf
