I have been diagnosed with mild lupus today and recently with hypermobility spectrum disorder. It is difficult to know which symptoms to attribute to which condition. I've had a really bad winter. Flu followed by tracheitis and a couple of other viruses. I'm ill again this week, temperature, rash, sore glands, headache, sore throat,chills. How do I know if I am having a lupus flare up? WhT does one feel like. It seems these past few months I always feel ill.
