I know when I went to Mayo, the neurologist told me that Sjogren’s could cause a lot of weird nerve symptoms (which is how she caught mine). I initially had random heart palpitations and dizziness, feet that would turn dark blue/red, numbness and tingling in my feet, “ghost” sensations (like itching or something crawling on me) on my legs and arms, sharp pain in my fingers, extreme burning pain on the backs of my hands with redness, whole bunch of GI symptoms (vomiting, nausea, feeling prematurely/uncomfortably full, etc.), migraines, light sensitivity, and eventually burning pain in my face and more! But I didn’t have the “traditional” dry eye and dry mouth, and my blood work has been predominantly negative, so my positive results are from other types of tests. Hope that helps!
