I decided to soak my feet in slightly warm water with dead sea salts later today, and when I took my feet out, I noticed a smaller, less than pea sized red lump on the bottom of my left heel, and the rugburn feeling rash/lumps on my second toe spread to the side of my big toe and to the top of my fourth
toe on my left
foot and the side of that
toe between the pinky and my fourth
toe.
I don't know what this is, but it seems to be spreading pretty fast.
