Merchant I understand carotenemia can affect feet as well as hands. It’s caused by too much Vitamin A and is found not only in carrots but also sweet potatoes, squash, citrus fruits, apricots and even green vegetables. Have you been eating more of these just lately? In my case as soon as I worked out it was red Romano peppers and stopped eating them I haven’t had it since. I did find it fades within a few days. If you are worried and if you have any other symptoms such as headaches etc then it may be best to see a doctor.
Somehow I don’t think it’s Schamburger’s disease as that affects the legs as well but I am not a doctor.

Have you even unknowingly put your foot in it?
