I am hoping this is not what my sister has. She has been complaining lately of pain in her abdomen, of feeling full of gas, and of having pain when she goes to the bathroom. I wonder if the doctors might be able to find something by searching for these lesions on her kidneys. It would be such a relief if they could find something using this method. I will be looking into this to find out if there are free procedures offered to those with little or no health coverage.
