For some time I've had an intermittent rash on my hand. If I remembered to use enough cream - mostly E45 - on it, it died down and then flared up again. Since just before Christmas it's been on the move and I now have rash on both hands, up my arms, along both legs and this morning it started in the small of my back. It's not a continuous rash, just little patches of raised red spots that then fade into a rough disc about the size of a 20p piece. It's very itchy. My GP has no idea, but has prescribed cortisoid cream and antihistamines. They help with the itching a bit, but haven't stopped the spread of the patches. Pretty certain that it's not a Vasculitis rash, so any ideas would be welcome.
