I have has surgery for kidney stones 4 times, laser. Once, I had the old basket therapy and they left a tube in my for swelling (that was the most painful) 7 times I have passed stones. I have 9 still in my kidney. I was diagnosed with spongular kidney disease. My kidney just makes them it doesn't matter what I eat. Now since I have CRPS I am worried that the kidney will get CRPS. Is that possible?
