My foot was itchy and getting kind of hard right in between my last two toes and it's been like that for a year. I recently went swimming, and since I've been to the lake my foot has gotten sore and achy, and I've been checking every night for 3 days and on the 3rd day my pinky toe is red and has a giant white mark in the middle. It's getting hard to walk and I'm always paranoid about amputation over little stuff.
