my doctor told me a few years ago that I had chronic kidney failure and not to take anything for pain but panadols I had a kidney scan showed my kidneys are very small when I saw my diabetic nurse this year I asked her about my kidney function she said it was very good for a women of my age...
I have had both mine done and I agree the worst part was the initial injection I was also able to watch the operation I had to rest my hand for a month then back to normal,
