I’m just wondering if RA can follow suit after being diagnosed with OA years before. I was diagnosed with OA almost 4 years ago. The reason I ask both of my pinky fingers have been achy for about three or for days now. I know with RA if a pinky finger one one hand aches usually the other does on the other hand does as well. I’ve had trouble with arthritis in my hands for the last few years but the way it’s acting it sounds like RA is trying to start now what does this sound like to you?
