Thanks, Nancy! Now I won't forget again.
Since your GFR, which is usually calculated, is low, you should immediately consult with a nephrologist. Don't be worried, however, since you are on those drugs and the kidneys filter waste products from the body (including drugs), you can't be too careful!
My dad had kidney failure. It was from high blood pressure due to a blown aortic valve after having rheumatic fever. What I know from his experiences is that you never gloss over any kidney issue. How's your BP?
Do you know what the GFR has been in the past? Can you track a trend, and see if it was normal before the drugs?
Is it possible that you might have lupus?
It makes me nuts when doctors gloss over important information! Go see a GOOD nephrologist and figure this out.
Don't worry too much, but do take action (which I know you will). Take care of yourself!
