Take a deep breathe and let it out slowly. Find out the facts before you let yourself fall into depression for something fixable. This is LIFE with Lupus . Your walking and talking , and aware, beats going out in an ambulance lol
I have been on Lisinopril for ten years. Doesn't stop the infections but works well for the protein.
If you can't fix it , just unbreak it !!! One day at a time honey.
