Hi, I been having micro blood in my urine and bad pain in my left kidney. The pain in my left kidney started a year and a half ago when my adrenal glands were removed. I had a cat-scan done and the results showed only scarring of the lower pole of the right kidney. I go to the dr Friday, can the blood in the urine be coming from scarring of the kidney that is scarred? It's my left kidney that hurts
