Lupus is called the disease of 10,000 faces because given a group of 10,000 patients, we can all have different symptoms & different lab work. SO yes, Lupus is
highly individual and difficult to diagnose.
Good that you are seeing a Lyme-aware rheumy - do you know if the rheumy is active with the local chapter of www.lupus.org
? That is how I generally tell people to see if their rheumy is interested in Lupus - not all rheumies are.
Lupies can definitely get high blood pressure and butterfly rash -- if your friend got diabetes from Lupus it would be rare, but it could be that her diabetes came from side effects of medications. (Adult diabetes type 1 is an auto-immune disease in and of itself.)
Hang in there till your rheumy appt, and let us know how if goes or if you have any other questions we can help with!
