Go see the PA, would be the best place to start. You need medical help. My GP has you see the PA as a new patient, then after tests are ordered you make an appt with him. PA’s are full of knowledge and experience. I have IGA Nephropathy diagnosed in May and my Nephrologist put me on 25mg Losartin. It’s a high blood pressure pill, which I don’t have but it’s a beta blocker that stops the protein. My Protein in urine has gone from 970 to 280 in about 4 weeks. I was told it will go lower once I’m on Losartin longer.
Good luck with everything!
