IMHO, you need more medical attention. Find the best Nephrologist you can with experience treating IgAN patients, and escalate through your insurance provider, if applicable, until you find that doctor, even if you need a referral to get there. I was diagnosed with IgAN and HSP vasculitis via renal biopsy in 2008 after tests showed very heavy proteinuria. My local Nephrologist in Atlanta was experienced but in my case referred me to an IgAN expert at the Mayo Clinic in Rochester, MN. I started treatment right away. I won't mention the meds or tests used because every case is unique. It took awhile to get my proteinuria and kidney function under control and my IgAN has been in total remission for 10+ years. My annual blood and urine tests have been excellent. Don't stop until you get the medical attention you need. Best wishes!
