I went to the doctor but he didn't tell me what it is but he is still doing tests. The only thing that worked for me was toothpaste then the doctor gave me some clear medication. The clear medication was better only because it wasn't sticky like the toothpaste. I suggest for the feet use something like GermX first. I know toothpaste sounds silly but it was a life saver for me.|||You might also see if it might be dermatographism.
