My daughter had a smaller version of this back I. Jan and after a 10 hour a&e stint and full bloods they couldn’t figure out the exact cause and as she had cold symptoms and fever they thought likely a viral rash.
she’s recently been poorly and it came back a little bit, now a few days later it’s back and worse than ever. No temp, doesn’t fade when touched and is well in herself.
it’s very hot today but doesn’t look like any heat rash I’ve seen …
