Help identify rash on teen please

[Rashquestions]

Dd15 has rash on chest and stomach. There since yesterday morning but only told me this eve.

not itchy, not hot, feels well in self but v v tired past few days. Any thoughts? I can’t think have changed anything to cause a reaction.

thanks

One more

Shall I keep an eye on or gp first thing?

thanks

Look up tinea versicolor.

I get it sometimes after I've been sweaty or hot etc on my back. Disappears with simple anti fungal cream from Amazon after a few applications.

Thanks. Have googled and not sure the same. Hers are more individual spots I think?

Pityriasis rosea?

Have you done the glass test? If does disappear will need to be seen by a medic. Any headaches/blurred vision/confusion

Came on to say this. I had it and it looked just like that.

Yep, pityriasis rosea. Made me pretty tired (or perhaps I got it because I was run down).

Somewhere he will likely have a "herald patch" - a bigger spot which will have come first. I had two- one on my neck partly in my hairline and one on my chest.

No need for glass test or any of that shenanigans unless you suspect sepsis or meningitis - and if he had those he'd feel bad.

*doesn’t disappear
