I have been seeing a lot of people recently with horrendously itchy skin. They often arrive with a diagnosis of dermatitis, psoriasis, eczema, urticaria (hives), shingles and at this time of year I've even seen a few cases of orf - which is a virus you can catch from sheep - all different complaints but the same endless painful, maddening scratching, often until their skin bleeds.

Over the next 24 hours the little girl re-grew her entire skin and her mum said for the first time since she was born it was perfect.
