I have a 7 year old grandson who has been having kidney issues for the last 18 months. Symptoms are, BLOOD IN URINE, SLIGHT PROTEIN IN URINE, ABDOMINAL PAIN, LETHARGIA, AND PUFFINESS AROUND EYES AND FACE. He is set for a kidney biopsy on the 20th of this month. No one can come up with a diagnosis. He has been on steroids, which do not seem to help, and symptoms can come and go. He also complains of body aches. Does anyone have any thoughts on this issue? Or does anyone have a child with same symptoms? Thank you Bella1950
