Treatments

My Mama was diagnosed with Sjogren's a couple years ago and I have all the same symptoms although I've never seen a rheumatologist to get a proper diagnosis. Her rheumatologist told her there's not really any treatments other than the Prolia (I'm sure I butchered the spelling lol) infusion she gets twice a year. In my mind, what's the point of adding yet another Dr to my lineup if they aren't going to do anything/there's no treatment, ya know. IF I decide to seek out a Dr I can promise you it won't be Mama's Dr or anyone in his group.

Can anyone give me tips on finding the best Dr for Sjogren's?
