To ask what these marks are on DD?

[HelenLaBloodyAnnoyed]

5 year old DD keeps randomly getting raised red patches on her skin that then become sore and often bleed (I suspect because she picks at them even though she says they're not itchy.) Any ideas what they could be?

So as not to drip feed, she has autism and they seem to crop up around times of high anxiety. Could anxiety cause such a physical symptom?

Could it be hives? My DD gets them when she's really upset/stressed out.

It looks like giant urticaria ( hives ) that has been scratched or picked at . Urticaria is caused by an allergic response to something that’s either eaten or come in contact with the skin .
I’d say you need to see your GP though .

Looks like a friction burn to me the type you get from sliding down the stairs etc

I would go with hives caused by stress/anxiety. I'm frequently amazed by the physical symptoms people can present with for so called psychological problems. They are not as separate as people think.

Try calming and relaxation strategies first. Then piriton to soothe and stop it itching?

They don't seem to have any correlation with anything she's eaten or touched, only with anxiety so I was thinking hives too. She's had so many before that people have asked if she's had chicken pox recently

I have a friend with autism who 'skin picks' - so the anxiety causes hives/eczema, which he'll then worry and worry until he's bleeding. Hes done it to the extent it looks like chicken pox before.

Psoriasis? Take her to the doctor.

They look like the hives my son used to get when he was anxious.

I have autism and when I'm stressed i scratch at myself and make myself sore. I dont realise I'm doing it at the time, only afterwards when my skin is red and and raised and sore.

These look exactly like what happens when I get stress/anxiety hives and scratch them.

Could your dd be biting herself? They do look suspiciously like two front teeth marks. Just a suggestion.

GP job that. I get hives bit they don't seem to be typical from your photo.

How big are they? (hard to judge scale from the photo)

They vary in size. She's definitely not biting herself as I've seen them at the very beginning stage when her skin begins to become raised before she picks at it.
