7 years after i had been diagnosed by an ace Rheumy in New York, I moved to NC and was seeing a new Rheumy in Winston Salem for the first time. He proceeded to inform me I did not have RA and that i should see a different doctor for osteo arthritis. He said he would take Another RA Factor test but since it was negative previously, and he thought my disease was not RA, it would be negative. (Fun fact: as many as 50% of RA patients are not positive for RA Factor). It came back positive and his comment was that he would accept me as his patient. I told him thanks but I was not accepting him as my doctor and hung up on him. I ultimately found an awesome Rheumy - so if you are not getting an answer that makes sense to you, seek another input.
