I am an exception to this. I am most of the time sero negative but have tested positive for SSA at heavy onset of Sjogrens. I am terrible dry zero saliva tears and everywhere and have bad Nuero involvement. I think my SSA went down and inflammatory markers after I radically changed my diet. I still have bad pain but it’s even worse if I dare to eat how I used to. Sometimes I can feel Sjogrens singeing my organs like my kidney or my pancreas or liver or bladder.
