About 2 years ago my doctor told me I had high blood pressure. He prescribed a low dose (5 mg daily) of Lisinopril. Over time I slowly had an increase in pain in my right kidney. For a while it was only when I lay down in bed, then gradually started to hurt in the day while working. I went to a urologist and he did ultrasound, cat scan, blood tests etc all came out negative. He said it was something in my diet so one by one I cut from my diet coffee, carbonated drinks like soda, chocolate, cranberry sauce, literally anything I could think of that might cause this kidney pain. The pain got worse and worse. Christmas day it felt like my kidneys were going to split open. I was so sick I forgot to take that Lisinopril pill Christmas morning. By that night I began to feel better. I have not taken that pill since and today (5 days later) I feel 100%. Last 2 nights I have slept like a baby. SO if you are taking this drug and your kidneys hurt this is your warning.
If you look up Lisinopril on the net you will see it says it is good for the kidneys, that is not always so. Eric

Tommyran,

the same thing happened to a friend of mine except it WAS his tongue that swelled. Drs. told him if he'd waited another 30 minutes to get there, he'd be dead.
