On my right foot towards the heel starting just on the inside of the foot wrapping underneath reaching across the bottom of my foot going up towards the pink toe and randomly cutting off right before my heel I have such thick yellow skin. The inside of my foot I am pretty positive it’s a corn? It’s raised and started small and I’ve just let it go but the pain is becoming unbearable. The entire inside of my foot on the side is red by the time I get home from work and it never use to be that way. The pain feels like my foot is being rubbed raw after a couple hours. The pain is located on the inside going directly across the bottom of my foot where my arch is because that’s another place it’s super raised thick skin. Can I use at home stuff to take care of whatever this is or do I need to go to a Dr?
