My creatinine levels are high, and have been for years. I don t know the numbers. The doctor just says hmmmm, we should try to figure that out, but does nothing. Should I be concerned? WHAT A LOAD OF SHIT! WHY DONT YOU TELL PEOPLE FROM THE BEGINNING THAT THERE IS A CHARGE.?? Typical, money-hungry doctor that doesn t tell you jack-shit, just gets you further in debt.
