The Diclofenac that you are taking causes both high blood pressure and can worsen kidney function. The diclofenac will interfere with your blood pressure medications and make control of high blood pressure much more difficult. I also recommend better control of your diabetes. I suggest a target Hemoglobin A1C between 6.0 and 7.0 %. Blood sugars that are out of control can lead to an elevation of the serum creatinine as well.
