I have so many questions about this. Do I have to have a PCP referral to make an appointment? How about health records? I have many problems, the most prevalent right now is swollen legs and feet and have been seeing a few doctors in my area but no one seems to be able to help. I have had sonogram tests (blood movement is fine with no clots), an echocardiogram (heart is working well), but my legs stay swollen and stiff. I also have terrible pain in my knees due to osteoarthritis and neuropathy in both legs (I have to use a walker). Must I diagnose myself? – how do i know which department at Mayo to start with? This is in addition to if they will take my Medicare and BCBS. Mayo has such a great reputation that I just feel they could help me get my life back. Thanks to anyone with any answers or ideas.
