Hi Amanda and welcome
I'm sorry to hear that you are being investigated for lupus though, at this stage, I am sure that you would be happy to finally find out what is wrong with you. I know I was when I finally got my diagnosis.
Diagnosis can take an awful long time as these diseases are pretty complex.
Has your GP referred you to a rheumatologist yet? That would be the best place to start.
It's also pretty useful to take a look at the "not yet diagnosed" section where you can find info on the criteria and alternative criteria for diagnosing lupus.
keep us posted on how things go and we'll be here to try and answer any questions you many have,
:hug:
