I'm confused about recent developments, all along i knew i had osteoarthritis. But my rheumatologist thought i had inflammatory arthritis. The only box i ticketed was my anti cpp test results. now she tells me it's ' Fat pads' . i didn't and still don't understand want that means??. i didn't feel like i could ask her because she was a bit 'off' that day and i felt emotional, so left. can anyone enlighten me?
