Rather embarrassingly (but hey, I've admitted so many embarrassing things on Mumsnet), I am covered in bites. And they're spreading - I found some behind my knee this morning. I blame the cat - I've got to blame someone, dammit - but the fact is that the inferiorettes (to my relief) and their dad (rather gallingly) all remain unblemished. I feel like a medieval leper. Is there anything I can do to root them out and track them down, apart from de-fleaing the cat? Is it in fact scabies, or a plague of boils, or something? Will it pass, or will I become one revolting morass recognisable at the Mumsnet party by my hooded cloak and tinkling bell? Should I - horror - go to the doctor?
