I spent a couple of months living in a flat with some fairly extreme mould, which manifested in me developing hives on my skin when exposed to the cold. Given that this was in the alps in winter, it was not ideal. Symptoms stopped as soon as I moved out.
Yeah, but we're all ill. I'm asthmatic but normally don't suffer, however have started to.
Obviously it's more likely my cold and blocked nose, but it's still got me worried.
