Are you being followed by a rheumatologist? Rheumatologist are trained to treat rheumatoid arthritis. And they also are trained to treat Sjogren's Syndrome.
I know you are in pain. I understand it. All of us on this forum are in pain. I've recently had an increase in mine. Sometimes a pain specialist can treat the pain better than a neuro or a GP. I hope this information helps you in some way.
