text: i have a sort of rash in my upper arm. is there a way i can get rid of them? they don't hurt or itch. they look like goose bumps they are on both arms and i've had them for a while. hydrocortisone is a steriod cream - so please only use this if necessary  most people have them - small, white, bumps - all you can do is regularly moisturise and maybe they'll go away with time?
