What could this be

[Sux2Buthen]

These are on my daughters lower back, they are between the size of a 5p/ 20p

Are they on her spine? Looks like a rub/bang

Has she spent a while in a car seat recently?

No she's been chilling on the sofa, i thought maybe she's bashed it.
I think I was just checking for reassurance it's nothing gross or to do with incoming illness! Thank you

Just a couple of red marks. Don't overthink things.
