Proteinuria symptoms and conditions

has anyone used low dose lisinopril for kidney issues? i'm having an acute attack of nephrotic proteinuria and the kidney doc wanted to start me on lisinopril but we are waiting to see my latest round of blood work. my blood pressure has remained low (110 over 70 average) and since i've had asthma and other respiratory allergies, i'm pretty sure i would get the dreaded cough.
i am otherwise healthy, all vitals are great, except for high protein in my urine and low protein in my blood. my kidney functions all test normal. the kidney doc thicks it may be resolving on it's own so why should i risk the side effects & toxins of lisinopril?

I have been on a very low dose of Lisinopril for about a month now in treatment of Proteinuria in my kidney and have not experienced any of the known side effects. I am, however, experiencing a very erratic menstrual cycle, namely spotting virtually every day. I have been to see an OB/GYN and it has been determined that my internal organs are normal. I do not believe that I am premenopausal and hormonal tests have confirmed that. I have read in this discussion string that a someone else has experienced similar symptoms. Are there any more women, who have experienced this problem? I may just go off the medication to test this theory.
