curved, thick toenails - hurt!!
I've always had very curved and thick toenails. They're very hard to cut with clippers because of the thickness. I've had bouts with ingrown toenails before, so I'm very careful not to keep the toenails too short. I'm in a catch-22 though - if they are short, they become ingrown and infected. If they are longer, the curves of the toenails on the sides press into the skin and hurt, and the toenail itself gets pushed by my shoe and is sore. I can't seem to win!
