I few weeks ago I removed my nail polish and noticed that I had a horizontal crack near the base of each of my big toes. Also right underneath each crack is a small pit in what I guess would be the outer corner (side of foot with arch). It’s worse on my right foot the pit is deeper and connected to the crack, as if the crack is kind of a roof over part of the pit.
The rest is here:
