there are so many different kinds of arthritis but my feeling is if you've got pain in your joints, swelling and/or deformity of the joints, it doesn't really matter which one they call it - they all HURT. I'd say you're in the right place here.
They diagnosed me with psoriatic arthritis even though I don't have psoriasis of the skin. My Dad did have the psoriasis very badly. Anyway - I have the pain, the swelling and the deformity and have gotten much support and good info from this forum.
What medications are you on?
Welcome and good luck,
