Yes I had high protein in my kidneys in 2014. I was diagnosed with lupus nephritis.
I was put on mycophenalate to clear the protein in my kidneys.
They are doing much better.

I’d check that with my rheumatologist and ask him a full check of my kidneys

Kidney problems are a common side effect of Lupus

Have you seen a nephrologist?
