i took aleve (naproxen) the night before i got blood work done and i had my creatinine checked. it came out to .99. could the aleve (naproxen) have messed up my results? could it have made it lower than it actually is?

No: depends on the lab but mostly a normal creatinine is about 0.99 and this would not be an abnormality. Aspirin like drugs lower the blood flow thorugh the kidneys and this would , if anything, raise the creatinine not lower it.
