I try to say Serum normal, it sounds less, um, negative.
I have had dry eye dry mouth for about 9 years now.
It is worst at night, and I spray my eyes and sip water several times a night, and run a humidifier 24/7 all winter.
I also take Evoxac and use Systane. and Keeping my nose clear is also important cause if I breathe through my mouth all night it is a horror show.
All that said, when I read about the dryness and misery so many people here have, I am humbled and grateful for my minor problems.
I did have to give up contact lenses too, which broke my heart.
However, all THAT said, the treatments for most of our problems are for the symptoms, unless you're taking Plaquenil, prednisone or one of the chemotherapies like methotrexate.
And you already HAVE some heavy duty diagnoses. AND yes on AI conditions often cascade, one leading to another and so on.
I have been diagnosed with IC (Interstitial Cystitis, inflammation of the lining of the bladder) which doesn't have a blood test, but instead is visually observed with a bladder cystoscopy! 50% or more of the people with Sjogren's develop IC, and vice versa.
You KNOW what you are suffering. Get treatment for the symptoms. A lip biopsy often reveals Sjogren's when the blood work is normal, I believe.
Keep us posted.
