DD (7) has just developed a bright red rash on her arm. It is hot to touch and turns white when pressed. There are a few bits at the edges that look a bit like hives but the main area is exactly like sunburn.
She is otherwise happy today but was knocked out last week by something (maybe flu). Had no energy, felt sick etc and still has a cough.
If it is 'just' hives I assume it's because she's been poorly but is it possible it is scarlet fever, or something else? Do we need to go to the GP tomorrow?
