My specialist told me a flare could be minor and hit for short period of time with symptoms as little as an extra ache - or as major as full blown attack on internal organs and last for months.
My GP says a flare is when the bloods results are altered and that there is proven activity of lupus. So when I see my GP with added aches, pains and generally feeling unwell he thinks it's not lupus!
It's all soooooo confusing. I'd be really grateful to read your advise please.
