I've been running 6-9 miles a day wearing an ankle brace that made one shoe fit a bit snug on the toes. I noticed after a week that my nail on my second toe had bruised from the pressure against the front of my shoe. It wasn't the black "runners toe" but rather just looked like a normal skin bruise that happened to have a nail above it. It was sore and red all around the nail bed and about 1/4 inch under the cuticle. Then, someone stepped on my toe and an immediately a white line appeared beneath the cuticle that looks as though the nail has broken beneath the skin and has shifted about a 45 degree angle and is putting pressure on the skin. My boyfriend had lost nail after nail from years of soccer and all have grown back fine. However, a friend had her foot stepped on and had to have the matrixectomy and now has no nail. Do I need to see a orthopodist? Do I try to keep the nail from falling off, bandage it or something? More importantly, I know it takes a while, but will I eventually have another nail grow in?
