I'm training for a half-marathon coming up in about a month. So far I've run a 5k and a 10k and a 10 miler coming up this weekend. The half is on April 24. I have gotten a wicked blister on the end of my second toe that has gone under my toe nail. I'm thinking that eventually the toe nail will come off. Should I help it along or just let come off on its own? When it grows back will be like it was before I started running? I apologize to any who are grossed out but I'm curious.
