Sjögren’s Syndrome: how do you manage the symptoms?

Hi
I see a rheumatologist next week for sjorgens syndrome. Last summer a sinus doctor I saw mentioned it to me and recommended I see a rheumatologist. I never had heard of sjorgens and I have never been to a rheumatologist. At the time last summer. My only symptom was very dried out mouth. I developed dry eyes only a few months ago. The otc drops for dry eye stopped working unless my eyes were just getting worse so my eye Dr recommended something stronger otc. It's better. He did prescribe me restasis but unfortunately even with my insurance it was too expensive so I could not get it. But my other concern is the body/joint pain I ha e been having. It's gotten so bad tonight is the first time I have been up all night. I do have a unrelated degenerative changes near my lumberspine which is causing other embarrassing issues but my other pain started actually even way before the dry mouth. It started very soon after my gallbladder surgery last January. It started in my upper back spasms and just painful. Worse now then last 6 months went to my shoulders that's very tender, my neck. Arms. I read a article about sjorgens pain being similar to fibromyalga pain. I wondering if anyone thought it was sjorgens related being this painful or maybe something else? I have wanted imaging, preferably a mri bur been unable to get it. I'm hoping next week the rheumatologist will order something. Also last summer my sinus doctor did order bloodwork some sjorgens antibody bloodwork 5 of them and they were all normal. Although now with my symptoms progressing I wonder what bloodwork now would show. Any feedback would be greatly appreciated. Thank you.
