It won’t go away. It just popped up like a month ago and a have the urge to keep trying to pick it constantly and it get it almost flat but it always grows back. It sometimes itches too which makes me pick at it more. I love flip flops and it bothers me when I walk in them so I pick at it a lot. My daughter has a few of these on her foot I noticed a few months ago. Guessing it’s a type of callus from the friction of flip flops/heels. Weird that it’s only on one foot. So I figured I’d ask to make sure.
