@bbk186 Just because of my experience, I would at least ask the doctor if they are familiar with CPPD. I'm not saying you have it. But it's easily seen on x-rays of the most affected joints. Then you have to just follow the protocols. How certain are they of your diagnosis? Are you going to give he Humira a chance to work? You'll have to be way more careful about being around kids and people that are sick. Even a mask doesn't protect much against viral diseases, like the cold and flu, not to mention COVID. And just because you or they have been vaccinated, also doesn't mean you can't catch it. May I ask your age? CPPD is more prevalent in people over 60. That's when mine first reared it's ugly head. I would let them do the ultrasound. If it's negative and you are doubtful you can always get one somewhere else.
