My PA had requested I see a rheumatologist before she would continue to treat me. I had already started myself on steroids by self diagnosing myself. I thought I needed to go to a top notch facility. Everyone knows mayo. Probably good Dr's elsewhere I just didnt know any. I had heard they didnt take Medicare. I called Mayo Phoenix and they take medicare but do not take medicare advantage. So I called and they gave me an appointment about 6 weeks out. I saw Dr. Michael Pham. He referred me to a cardiologist and a urologist. Both saw me. I have tried to see a gastrologist but they wont take appointments. If they wont give you an appointment, you can set up an account and they have a message center. Try messaging one of the Dr's and their staff will respond. I dont know anything about any of the other Mayo sites other than phoenix and scottsdale.
