So I have had these red, raised non itchy bumps appearing on my arms and a few here and there on my legs over the past week, My Dr said it was known as "winter itch" and gave me a cortecosteriod which I've been using for two weeks and nothing it changing. I went to see him last week and he has now given me an antibiotic that I am take 4 times a day app-cephalohex and this also seems to be doing nothing. Could anyone enlighten me on what these are they are not bother some other than being visually unappealing. Thanks so muck.
