What could this be??

Hi everyone.
Last Friday (20th) I noticed this red blotches , they very dry, very red and really sore and starting to crack. As far as I'm aware she hasn't touched nothing different. We've done the same thing and been to the same places as we would normally. Nothing new that I can think of. I took her to the GP last Monday(22nd). They've prescribed her with steroid cream for a week. But nothing has changed and still the same. I've never seen anything like this and had a look on Google and can't find nothing.
Thank you for reading, I've attached some photos. X

It looks like she has held something, from the pattern of the fingers / thumb.

Maybe a tree branch or something the shape of a mug.

It looks a bit like a burn too but as you have been to the GP

Sorry no idea. Link to plants that can cause irritation.

Looks like post group A strep peeling. Symptoms of the virus can be very mild. One of my girls always got it after she'd have a slightly sore throat. It happens a couple of weeks after the illness.
