What are all the forms of inflammatory polyarthritis?

[Guest guest]

I have been diagnosed with Primary Sjogren's for almost 14 years. My

rheumatologist still believes that I have Sjogren's but because of

the appearance and pattern of my joint pain, he put the primary

diagnosis as Inflammatory polyarthritis, not specified and ordered

even more tests. I know that my RF has been negative for more than

14 years, and even my sed rate is never elevated (although I have

been on DMARDS for 11 years too). I was started on MTX last month

and he was seeing me this month to check on the medication change. I

was saying that I think it is helping me and then he noticed my hands

and didn't like the way they looked. He said my joints look swollen

and when he checked them, many of them did hurt. Of course, they

have been hurting on and off for over 14 years, along with having

stiffness, and very occasional redness and heat. So now I am asking

what are all the different forms of inflammatory polyarthritis and

how much difference does it make if I was incorrectly diagnosed all

these years? I have been on plaquenil for over 11 years and been on

cortisone in one way or another on and off (mostly on these last 4

years in low doses). I am now on MTX at 10 mg. once a week.
