<s>[INST] 40 yrs + , Ninpthrologist  evaluated me having tiny benign cysts on my kidneys that may cause the unseen blood in my urine. But 10 yrs  before that test, I  was prescribed  Piperacin Medi  by company Doctor  for complain lower back pain when I  ate salty food. I was on that medication for 3 to 4 yrs. when the was gone. The unseen blood in urine was seen 6 yrs. later . The situation  is the same until now. Is the blood in urine is  cause  by  benign cysts on the outer surface of kidneys? [/INST] Hi, the blood in the urine could be due to the infection, or may be the cysts, that is to be confirmed by the nephrologist. Don't worry you will be fine with the treatment.                          Take more of green leafy vegetables, pulses, sprouts, and proteine rich foods besides medication. Thank you. </s>
