Protein In Urine With Fever

I've had all sorts of tests. and protein levels greater than 500 with varying grades of fever for 4 weeks. Tests have shown this is non bacterial. If ( as I hope) it is viral, how much longer can I expect it to last? I have done my research and am self pay. How long should I wait for more extensive testing? My doctor is out on medical leave and I have clotting disorders. I really am getting tired of explaining my situation to her replacement Dr.s and paying $ I can not afford right now
