Hi, I've had a rash for around 8 months now. At first I took it for ringworm, although I was mystified as to how I could have picked this up (no children, no pets) and my doc confirmed that's what it looked like. After a few months of treating it with anti-fungal creams it just kept spreading. I mentioned it to my doc again and he said it looked like it might actually be Pityriasis Rosea. After looking it up on Dr Google, it did sound like a better fit, so I stopped using the cream and nothing happened. No better, no worse, so not ringworm after all, I'm guessing.
I had the 'herald patch' on my chest first then large red blotches appeared on my thigh, then my arm. I now have it from my shoulder to my knee, all down the right-hand side of my body. It's very localised to just that area. It is much worse after a shower and does have a slight scaly feel in places. If I scratch it inadvertently, (some patches do itch, others not), the skin comes off alarmingly easily.
However, the most significant thing about this is it's only supposed to last a few weeks. In bad cases it can last five months, maybe six. I have had it for at least 8 months, with no signs of abating. As I have several 'issues' (trigeminal neuralgia, subclinical hypothyroidism, anaemia and neutropenia, plus I am on Carbamazepine, which produces loads of drug-related illness), I have NO idea which one might be causing this. So I'm asking on each of my forums to see if it might go with one of these conditions. I should just mention I have B12 injections once a month, which are being used to control the pain of my trigeminal neuralgia, which they do very effectively, so I have, or have had, some B12 deficiency, although I am not exactly sure why.
I'm not absolutely sure this IS Pityriasis Rosea, of course, and my doc couldn't care less, so if you have something like this, or have had it, I'd be really grateful if you could give me any information on which condition, if any, might be to blame, and if there is anything that could be done to clear it up.
