daughter has woken up with a rash over both arms

[NamesNick]

dd has a rash all over both her arms. she feels hot to touch.
she seems ok in herself apart from saying she is tired.
she had disturbed nights sleep last night - woke up about 5-6 times...

any idea what this could be before I call the doctor at eight thirty?

should I leave it and see how it progresses?

It could be a viral rash, my two often get these when they are fighting an infection.
Id ring the gp though.

Im assuming you've done the glass test though- roll a glass over it and see if it flattens/ disappears or stays raised.

glass test...rash disappears.

will phone gp surgery now

Hope your dd feels better soon

Thanks for help
