Ds6 complained about a week ago that his side was itchy. I found a little group of what looked like mosquito bites so put some hydrocortisone on them and didn’t think any more about it.
Ds just knocked his side playing and starting crying that it really hurt.
It now looks really nasty. He says it only hurts if I touch it. He seems fine in himself.
He also has another little group of spots on his back like the original ones. Patch is about the size of a 10p
Any ideas what it could be?
