Hi Dr De'Eath
I know you've mentioned your leg before and I don't think anyone on here would presume to try to diagnose you, other than saying "have you thought of this, here's some pictures" and I'm sure your GP is clued up. I know I mentioned Necrobiosis to you, when I had a small patch the GP didn't know much (if anything) about it, but the nurse did - the nurse at my GPs is very clued up indeed. As he's taken a biopsy one would hope that would give some clues at least.
I was just wondering if you've had thyroid tests and if so what the results were, cos underactive thyroid can cause nasty dry skin.
