I have weird toenails anyway (from my grandmom it seems).. but my 2nd toe on my left foot.. for years.. there is this one crack in it that goes down to about 2/5 of an inch from the base where the cuticle is. I let them grow, and it'll stay together alright, but I have to be VERY careful when I clip my toenails, or if I walk into something.. it'll knock out the entire top part, either the right or left half of that toenail. It's about the length I like to keep it now, and you can look at it and see the crack.. any suggestions?? Thanks so much!
