My dd2 age 6yrs has had this strange thing twice now.
The first time she suddenly had 4 symmetrical marks on her back, 2 on her spine and 1 under each shoulder blade. By the next morning they had turned into grazes or burn marks ( they weren't it just looked like this). They went and have now faded.
Today (about 6 weeks later) she had a patch of red raised bumps at the base of her spine which have now also turned into a burn looking mark.
She isn't bothered by them and they are not itchy. Does anyone have any idea what this could be? It looks pretty red and angry.
Many thanks in advance
