I've been dealing with something weird going on with my foot for the past few months and Im a bit worried. It started with a sharp pain in a specific spot under my right foot and at first, I thought I just stepped on something by accident. But then this small, pea-sized area developed extra layers of skin and eventually formed a kind of hole. Theres no blood or pus, but it hurts a lot when I walk. Oddly, when Im sitting or sleeping, it sometimes feels like nothings wrong. If I poke that spot though, the pain is pretty severe. Ive been walking slowly to avoid putting pressure on it, but now thats messing with my knee. What could this be? Any advice on what I should do?
