Hi I don't swell much either, just slightly swollen everywhere but with one flare my CCP was 350 and I couldn't get my jeans on, my knees were huge. I think the meds especially mtx keep the swelling down.
I guess thats why we take all these toxic substances so they stop the damage caused by the swelling.
My rheumy seems to see swelling when I see nothing.
I wouldn't worry its the symptoms they go off.
