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.

I took myself off methotrexate for psoriatic arthritis without my doctor knowing it. I was on arava and enbrel and my enzymes were slightly elevated. I want to see if psoriasis comes back. If it does and my enzymes go down, i will start start the medicine
