Nor have I but there are a lot of things I haven't seen and my knowledge of bloodvessels is limited. However, I think it is far more likely that some bacterium has travelled down the latter than that the kids have beaten themselves up in some way and I can't think what way. GD loves school btw and certainly wouldn't want to miss it I would accept that it might be due to some activity that both had been involved in (though can't think what) except that GD was certainly not involved in any activity (other than hanging around hospital) in the day between the lesions appearing on the first and second arms. .
I sent the photo to the dr. who writes on medical issues at The Times (they invite questions) and he thought it might possibly be contact dermatitis which I still don't buy. Haven't told him latest development. Still a mystery.
