My ccp ab IgG came back at 221, sed in january 15 to now at 50. I was then put on prednisone until I see the RA may 6th. What my safest treatment?

See details. I personally hate it when a pcp starts prednsione before i see the patient because it hides all physical finding. However, your lab results strongly suggest ra. I would stop Prednisone until the rheumatologist sees you.
Difficult to say. It depends on the results of other tests that you rheumatologist will perform as well as your history. Difficult to say without knowing more.
