lol wtf. Go see a podiatrist prime before your fungus toenail falls off 
You mistakenly pictured Muscle Matters feet in your response. His feet look great. There's nothing wrong with them except that they seem rather small. My guess is he is fairly fine boned which helps account for his great symmetrical physique.
Yeah well, I do occasionally see a podiatrist mainly to get them professionally trimmed. This service is free for seniors on Medicare whereas a pedicure at a salon cost somewhere around $50 plus a tip.
Unfortunately, there's not much that can be done for the big toenail on the right foot. I smashed it so many times by either dropping something on it or stubbing it, that it died. When I was in my 30's a doctor cut it off completely to the quick. Not a pretty sight. He said it would grow back normal. He lied. It never fully reattached to the toenail bed although it has gotten marginally better over many decades. The whole toenail used to be black.
Anyway, it's not toenail fungus you are seeing, it is a dead toenail. I almost wish it would fall off. It is a real bitch to trim. I almost need a hack saw to do it.
