Hello doctor, I had a blood workup done yesterday in preparation for a chemotherapy port removal. My creatinine level was 1.9 mg/dL at that time, and it has been within normal range before that. I had significantly decreased urination the day before but had a lot of sweating the preceding day. I had to avoid food and water for eight hours before my port removal procedure. My urine output and fluid intake are back to normal since yesterday afternoon. I do have uncontrolled diabetes, history of high blood pressure and some edema in my ankles. I currently take Avapro, Imdur, Plavix, Metformin and Insulin for the heart problem and diabetes. A nurse called late today and suggested me to visit ER, because of the creatinine level and the decreased urine output for that one day. Is a trip to the ER necessary? Or can I wait for two days and go to a doctor's office then? I am on a limited income so I would rather avoid the expense of the ER, if it is not necessary.
