I have pain in my legs and my toes turn bluish when I am seated for long period of times. My cardiologist referred me to a vascular radiologist who gave me an appointment at the radiologist s office today. He was supposed to do a Doppler. My cardiologist then scheduled an arteriogram for Nov. 3. They called me from the vascular radiologist today and told me that the technician was not coming today since he was sick and that they could not give me the appointment until Nov. 5. That is two days after I have the appointment with the cardiologist for an arteriogram. My question is this: Should the Doppler be firs or it does not make any difference. Should I report to the Cardiologist that my appointment at the vascular radiologist has been changed? Please help me out.
