My mother had PKD. I am in my 30's and had an ultrasound. It showed 3 cysts on each kidney. I think 1 or 2 were slightly big. I am seeing a nephrologist soon to discuss this. I don't have any symptoms of PKD except that I'm very tired always and urinate a lot. But I have other illnesses that cause tiredness. Also I had an ultrasound about 12 years ago and I think the results were the same or similar - 3 cysts on both kidneys, 1 was slightly big. Do you think this is PKD? I also have low blood pressure, too low lol.
