I'm not sure if this is anything to worry about or not 
on putting DD to bed I've just noticed she has a faint small pimpled raised rash - right across her torso, back & front - & looking in the light I can see she has more on her forehead - hidden under her fringe - its pale, barely any colour, but can be felt, at first I thought goosebumps, but its a definite rash though only very slightly pink - needed strong light to show that up.
She has been a bit snuffly this week & also has diareah, but diareah can be normal for her - though usually for a food or stress reason - none I can think of, ATM - though she was travel sick on a day out yesterday & I wondered if that had unsettled her stomach - though it wouldn't usually - also she's not been travel sick for a quite some time & it wasn't a long journey, so that in itself was odd 
She is a bit under the weather, cold & clammy forehead at times, but doesn't seem to have a temperature, but does look pale with dark circles on her eyes
Not sure why, but measles popped into my head on looking at her - though she did have single jabs, she didn't have her booster due to needing to be well to have it, & there not been a window where the jab people have been in town when she has been well - though School nurse (who I've a lot of respect for) did say I was doing the right thing, due to DD being ill a lot at the time.
Does this sound like anything?? - she's generally not prone to proper rashes like this & has had chicken pox & german measles
Thank you :)
