My little brother has an unknown kidney problem, but the doctors haven't been able to say exactly what it is. When he starts to feel really sick his eyes and feet swell up really bad. At times he could barely even see from all the swelling. Also when peeing it hurts. Do you have any idea what it could possibly be? Or what we should ask the doctors to look for specifically?
Does he see a urologist yet? He needs a proper diagnosis. Any blood work? What are the numbers?
