I am seeing a lot of post on kidneys. I found my kidneys both were scarred back in April 2014 from a sono. I had protein and blood in urine. Or is the protein in my blood. Anyway, I had low end lupus diagnosed with a low ANA. I spent quite a bit of money to get another blood test in August 2014, blood work showed nothing. Everything normal according to rheumy and no lupus according to rheumy. My question is, do I have to worry about my kidneys getting further damage? Should I follow up with a different doctor? I think my kidney dr is a jerk. He didnt even tell me to come back in 3 or 6 months with scarred kidneys already documented. I get back pain here and there which I generally ignore and attribute to tissue tightness in my back. Should I find a new kidney dr. And at the least check my kidneys to see if further damaged in 6 months or a year from original sono? What are the normal check up routines for lupus patients? Thanks for any advice. Don't want renal failure pop up on me one day.
