Can she ask to be tested again?
That is CRAZY that her doctor took her off of her medication--with her severe RA! Wow. Can you find her another doctor? I know it's easier said than done, but she should not have to suffer!
Seriously, at 77 years old, you should be able to not have to worry about pain control. WHAT is this world coming to? Please, find another doctor to treat her!
