I've been taking Advil a lot for pain and I think its the reason one of my blood levels has been fine and why I haven't needed a procedure since May. The thing is I have kidney disease and shouldn't be taking Advil. So I'm worried even though my red blood count is good, I messed up my kidneys even more. So I'm currently not taking the Advil. I'm not sure what my red blood count will look like in 4 weeks or what my kidney level will look like in November, but I may have some explaining to do to at least 3 of my doctors.
