Hi Also a Welcome to the site hope you get a lot out of being here
and yes Blood Work can change RA can be Sneaky
the Tendon issues can be a Downer I think I've spent more time dealing with other issues than joints
Tendons muscles internal organs etc. etc. people hear any form of Arthritis and think Joints Only
But it is SO Much More ,
I have my Blood Work up Minimum Monthly and Every time it is Different
so that's probably why your Dr is going to Look at RA Latter
