Hello..I'm 49 and I have Lupus, it seems like I've had it for most of my life and if I wasn't DX yet then my sister , mom and grandmother had already been DX with it. I can only tell you with all of us and several friends of mine with Lupus always seem to have what the Doctors call a low grade fever.
With Lupus your immunity is very low, I would call your GP and let him/her know about your throat and eyes, the Doctor might want to start you on something even before you see the Rheumo Doc.
If you have any more question there are alot of us who can try to answer them for you.
BTW welcome to the wacky, weird, world of Lupus.
