What could my doctor be overlooking? ANA 1:1280

Hi!

Posting on here in hopes that others have had a similar situation to mine, and may have some pointers on additional testing to request from my docs.

There have been times I’ve had swelling in my wrists/fingers, I get tested during these symptoms and inflammation markers are normal. I had back pain (that turned out to be a bulging disc) that initially made my doctor request autoimmune labs.

Any pointers on other rare autoimmune diseases my doc could test for would be appreciated. I was on Plaquinel for three years because of my low positive DS DNA test. The medicine did nothing for me and I’ve been off of it for over a year. My labs have since been normal even after stopping the meds.
