There are false positive RF in significant amounts. Yours could be a false positive or you could have both psoriasis and rheumatoid arthritis. PSA can elevate sed rate & CRP. Are your fingernails pitted? If you're female, I favor RA& psoriasis. If male, PSA. . However A rheumatologist is best to advise you.
