My son has had this all over his tummy, back and tops of legs/bum since last Sunday so a good 6 days nearly a week. He says they aren't itchy, he's well in himself other than feeling more tired than usual/darker circles around his eyes, I had him at the doctors and even the doctor was stumped, he requested a urine sample which won't be back till Monday now. We've stamped out allergies as far as we are aware, Does anyone have any ideas? Because they aren't going away I've never known rashes staying put for all this time. They look kinda yellow/skin colour more than red or pink
