My 18 month old has a very itchy rash (red bumps) on his hip, crook of one arm and leg. We tried using hydrocortisone and lotrimin but it is spreading down his leg, under his arm pits and to the other leg as well. He s pretty itchy but no fever. We started using a perscription cream (can t remember the name) but I think it s a steriod that we use twice a day. It doesn t seem to be making a difference. Finally, the original locations of the rash are now like one big red spot that looks a little purpley-yellow as well, The red bumps are what is spreading. Please help!
