I would like to state, for the record, that I'm ignoring the idiot advice nurse.
It turns out the oncology/hematology doctor who is supposed to be dealing with the mystery anemia is out this week. I had an incredibly annoying conversation with his advice nurse, who kept concentrating on the shortness of breath, not the joint pain, and insisted I should see a doctor today and have someone drive me. There are no appointments anywhere near me, so she wanted me to go to an urgent care place and wait. Then she keeps reading a list of urgent care facilities I could go to, revealing that she has absolutely no grasp of Atlanta geography.
The shortness of breath is the same as it's been for weeks. I've managed to go to the grocery store, Home Depot and other errands without passing out. It's the pain I need help with. Instead I get someone asking me five different times if I've had surgery and if I had a history of heart disease.
Also, one reason this thing was such a clusterfuck in the beginning was that I kept seeing different doctors. I'm going to get an appointment with my PCP this week so that at least there's not another doctor in the mix. I don't know what good it will do, but she can order a blood test.
