Hello and welcome Loretta;
I am sorry that you are stuck in the diagnostic merry-go-round right now. Diagnosing Lupus is quite difficult and can sometimes take more than a year. The diagnostic process is lengthy and is really a process of elimination. There are so many auto-immune diseases and their symptoms and test results are very similar. As such, doctors are loathe to make a diagnosis until all other possibilities have been eliminated.
Fortunately, your doctor is treating your symptoms while you are in this process (there are many doctors who refuse to treat symptoms until a diagnosis is made and the patients have to suffer for months). I know that you want answers, but in the arena of auto-immune diseases, answers are not easily had.
However, we are here to help you as much as we can throughout this ordeal and will do what we can to provide you with support. I do wish you the very best.
Peace and Blessings
Look For The Good and Praise It!
