She might've for a couple of days, but not for very long if she did. She could barely hold her son, that's what sent her searching for an answer, though I'm sure she has suspicions, since her mother also had RA.

As far as I know, those are not her x-rays, as none of her fingers seem that out of shape. She was able to enter a drug study not long after she was diagnosed, and it has done wonders, you almost wouldn't know she had RA(if you didn't know her, or see the scads of pills she takes)

That's why they used her for the clip. They picked her and another lady to talk about their stories, both before and after entering the study, as they're getting ready to get the drug approved for general use.
