Re: Weirdest thing!!!
This sounds like what happened to me. I did a 3-day, 60-mile walk back in September and got a blood blister UNDER three of my toe nails (the second toe on each foot and the big toe of my left foot). Like Marti said, after the blood dried, all three nails fell off (completely painless, by the way). The two smaller nails have grown back and they look normal. The big toe nail is still growing in. That's taking some time. I saw a foot Dr. back in Oct/November and he said the nail will never look the same. Thank God he was wrong. Especially for me, since I live in So Cal and it's sandal weather! I had a pedicure a couple weeks ago and had the nail painted for the first time since it fell off. It looks a little different from my other big nail, but I'm probably the only one who can notice.
Once the nail falls off, the surface of the toe will look gross. But it'll get better.
