I have a faint rash on my lower legs, upper legs, upper arms and lower stomach, it is very patchy, not in big blocks, however when it gets warm it becomes itchy, I have to itch so much it bleeds, my doc thought at first eczema so gave me streroid cream, which made it much worse, then she thought maybe an allergic reaction to carbimazole which I used to take for my thyroid, however I was on it for 7 years without issue, I stopped taking it 3 months ago, however the rash while better has still not gone, it is considerably worse at night in bed, when I scratch lumps small lumps come up under the skin
