It is good that you are educating yourself about Lupus, but you cannot force your doctors to give you a diagnosis. As I mentioned in an earlier post, perhaps you need to find different doctors.
As we are not doctors, we cannot give you an answer as to weather your rashes are due to Lupus or not. Tests must be conducted in order to make that determination.
Please consider following some of the advice that we have provided here in order to lessen your frustrations and to possibly get some answers!
I wish you the very best.
Peace and Blessings
