Do you have an explanation for small, itchy, spaced out, red bumps on my feet? The diameter of each bump is about 2 mm, so I don’t think they are any kind of mosquito bite. These bumps only have effected the feet. Minuets ago, I began itching my left foot . The right foot also has bumps but I have been careful not to scratch them, therefore the right foot is a lot less itchy. Please, do you think this is a kind of rash? What is it caused by? How can I make them itch less?
