so i've had thi odd patch of slightly rough skin on my foot for years. And lately it's gotten much bigger and rougher. Since I had a doctor appointment today, i asked him about it. And the leading theory is that it's basically a callous from sitting with my foot tucked up under me all the time. So I need to try not to do that if I want it to go away. This is hard. That's probably my most common position when seated. I'm debting whether it's even worth it.
