Unfortunately, we aren't doctors just regular old Lupus patients so we aren't even qualified to "guess".
Don't know what your "lumps" might be. Are they hard or do they have fluid in them?
I don't quite understand your Dr saying "it's not Lupus cause you don't have a rash" -- that's pretty crazy, Lupus comes with and without rashes, it isn't really that common a symptom.
Your blood counts being so low & out of range seems like it'd be some sort of blood issue, and that would certainly account for you feeling like crap. We don't function if our blood isn't doing it's job!
Hang in there till your appointment -- perhaps you could call and get on a cancellation list and maybe be seen sooner?
