I went to the doctors to have a urine test for an internship and they found protein in my urine. My doctor prescribed me with an antibiotic for a week and that reduced the amount of protein enormously but not completely. Then he told me to drink plenty of water for a month and come back to see him. Well there is still protein in my urine. So I have to see a nephrologist. I am very healthy and active and Ledbetter disease doesn t run in my family. I also noticed that I have been having really bad cramps when I go running and sometimes they continue even after I am done running. I looked up random stuff that I eat or do that could be causing my cramping and I came across that soy milk can cause cramping and cause malabsorption of protein. Could the soy milk that I drink everyday in my coffee be causing the protein in my urine?
