A few days ago I started noticing small skin colored bumps appear on my arm and throughout the day more appeared, they didn't itch or bother me at all, until the next day they started itching, and the day after they got bigger and now they are red patches, they're not scaly or rough, and more keep appearing, as they appear they start as small bumps but the new ones that appear are itchy, they are all over my body some in clusters and some by themself, I don't know what it is but I'd like to find out in fear of my child possibly getting it
