Welcome @greenacressoon, I'm a Mayo Clinic Rochester patient and have seen rheumatology and other specialist when getting a referral from my local Mayo Family Health Clinic near Rochester. I first saw the rheumatologist when I got a referral from my PCP for my PMR prior to being diagnosed back in 2007. I only saw him a few times and I'm sure I would probably get a different rheumatologist if I needed another referral just due to new doctors coming into the clinic. I'm assuming after your rheumatologist has more tests done and meets with you, she will hopefully suggest/start a treatment plan and you won't need her anymore unless something changes which would be where a local doctor/rheumatologist might come in.

Can you ask her what the rheumatologist that ordered more tests and will be seeing you again what seeing patients long term means to her? Also, the Mayo Patient Portal can be helpful if you don't live close. Have you signed up to use the Mayo Clinic Patient Portal?
